What blows my mind is not just that dinosaurs ruled the Earth but that they did so for hundreds of millions of years - a duration that no-one could even imagine. Such a long time that the dinosaurs of 65 million years ago must surely have evolved from a much more primitive version of animal? 🤔
@@gsk5161 At any point in time during the 100 odd million years that dinosaurs inhabited the planet, if it had been visited by aliens, they'd see that our planet has no intelligent life and fly off home.
This is a lie though, dinsosaurs were actually created by the bigfoot empire. They were super advanced but their biological creations developed disease that wiped them out, well most of them. Government keeps this the secret of the bigfoot empire from us.
I grew up in Illinois. We have great limestone beds which extend from Pennsylvania in the east to Iowa in the west and Kentucky in the south. This was caused by calcified remains of sea creatures in the Devonian and earlier. Evidently the land turned swampy later and dead vegetation turned into the massive coal beds from heat and pressure over millions of years. I used to find fossilized crinoid stems around an abandoned quarry. We also had an abandoned strip coal mine where there were fossil ferns inside rocks which had once been mud lumps. Very interesting.
I''m in Illinois as well and when I was a kid we would inspect the gravel in little used or abandoned railroad lines around our towm and find all sorts of fossils, mostly crinoids in the rocks used for drainage around and between the tracks.
@dougaldouglas8842 No silly.. The vegetation did rot and turned to something like MODERN peat moss, which under pressure and heat over eons of time- turns to COAL. As for oil, it is often found near salt domes or area where seas are or once were., In that case the plants and animals rotted on the sea floor liqufiying under mud , rock , and other debris until it sank and occupied pourous rock in seams or pools.
The Wenlock Limestone of Dudley contains the most diverse and abundant fossil fauna in the British Isles: over 600 species of marine invertebrate, representing some 29 major taxonomic groups. The Wenlock Limestone of Dudley is a fossil lagerstatten, containing rare and important life assemblages, in the form of beds of articulated crinoids (sea lilies) superbly preserved under deposits of terrigenous mud and volcanic clay. Rare annelid and early plant remains have been found, containing soft tissue. The site is the type locality for 186 species of fossil; more than any other British site). 63 of these are recorded nowhere else. Many new taxa, particularly of microfossils, have yet to be described. Dudley’s fossils are among the most perfectly preserved Silurian fossils in the world. This is reflected in the fact that they have always been highly valued and are found in countless museum collections and displays across the globe. Other superlative features of the site include bioherms (fossil ‘patch’ reefs preserved ‘in situ’), and expansive ripple beds, which provide evidence of littoral zone conditions. I live near Dudley which is in the in the middle of england and the aera is also known has the black country.

The headline is misleading. The video is largely about geologic periods rather than "bizarre creatures." We might note, however, that Devonian life forms were not "bizarre," but well-adapted to a climate that no longer exists. No doubt, we would look "bizarre" to them if the roles were reversed.
Great video! It's always fascinating to speculate about what our world may have looked way back in time. The idea of a world covered in ferns and mosses, with towering trees and giant insects, is both thrilling and eerie at the same time. It's amazing to think about how drastically our planet has changed over millions of years and how life has continued to adapt and evolve.

A very interesting point about the first plant life on the surface of the planet is that a lot of them are still around today just showing how much more resilient the simpler forms of flora and fauna are compared to the more complex and codependent life forms. We THINK an example of the first plant life on the surface was a relative to a modern plant known as Liverwort and they are mostly unchanged from their fossil record sample cousins dating back to 500 million years. You can walk around and find them almost everywhere (at least in the Northern Hemisphere) happily growing out of rock beds of sandstone hidden in the shade just like their ancestors hundreds of a millions of years ago did.
7:51 This makes me think: wow, these things are our ancestors! Everyone today - people, animals, my dog, that tree - everything is possible because of these little things! Mind blowing🤯

Yeah, the more I learn the more I realize we are utterly meaningless as individuals but have a massive impact as a species, and the things we do that ruin the planet for our own convenience are super selfish and we would have no need to explore space for another rock to live on, if we just took care of our own and were responsibly intelligent rather than recklessly intelligent
A nanospeck on a nanospeck is pretty solid, but realistically we are probably a nanospeck on that second nanospeck. Haha. It's comical that we as a species think we are special enough that anyone, if they existed in the cosmos somewhere, would even look at us as intelligent. We're just less hairy apes when it comes down to an outside perspective, were one to exist.
@@goosenotmaverick1156if we are meaningless as individuals who care what we do!!! Why should we have morals if we are meaningless!! We should just do whatever makes us happy since there’s nothing left after we die! The utter ridiculousness of evolution!

Also sounds to me like you have some knowledge of the Bible, and you choose to reject it and choose to believe what these people tell you happen with no evidence no proof just theories of things when no one was around to record anything, oh yeah wait we still hadn’t evolved enough to keep records that’s why there’s no record of what happened right!!😂
From the end of the dinosaur extinction some 64 million years ago and the beginning of "humans" some 5 to 7 million years ago, what did our Earth look like to our alien visitors? Great video as always.
The Devonian and the Cambrian animations always brings me back to my Child Craft encyclopedias in the 70s. The pictures in the book were like animations within my mind, and definitely patterned some neural networks in there.
What about the Mushroom Era, where Lichens/Mosses, and mushrooms, maybe some ferns were the only "plants". Before more complex plants/trees even existed? They broke down the barren volcanic rock into something plants/Ferns could root in, and then the plants dying created the soil.
By the time this planet becomes uninhabitable again (which it will), if you measure the Earth's whole lifespan as a 12 hour clock face, life would only have been possible for 4 minutes.
This isn’t true…. The oldest known fossils are 3.7 billion years old and models show the earth should remain habitable to life for anywhere between 1 and 2 billion years more. Meaning at worst the earth over its entire lifespan would of held life for 4.7 billion years. The earth is expected to be destroyed in about 7.59 billion years and has been around for about 4.6. So that is a expected 12.29 billion year life span where life was possible for at least 4.7 billion years of it. Which means on a 12 hour clock face, that’s over 4 hours. No idea how you reached your claim.
Really enjoyed that. Just returned from the dinosaur trail in Western Qld when much of Australia was under 60m of water around 100 million years ago. Fascinating.
This is an awesome video idea, i always wondered about this, you'd read about it in text books but visually it's far more captivating. Yes, please more of videos like this one, i enjoyed the work on graphics, wish this video was longer than 16 minutes.
It is amazing how, as each year goes by, the scientists discover and reveal new facts about Earth's history. Whilst many things are debated, as they should be, intelligent extrapolation leads us ever nearer to clarity about our past. Hopefully erasing superstitious nonsense and folk tales along the way. Science rules. Something we need to keep reminding ourselves of in these insane times.
Unfortunately, politics rules over science. That's how we can have this wonderful video which accurately depicts how Earth's climate has changed throughout its entire history, and yet, you'll still get people believing that man is causing a climate crisis, and they'll say that 97% of scientists agree without even thinking about who funds those 97% of scientists who are agreeing, or that it's usually the few scientists who discover the truth and have a hard time getting people to believe them (like Galileo). So yeah, money rules... politics rules... science is somewhere on the bottom. Right now, science is nothing more than a tool to spread mass propaganda.
Thank you. Very enjoyable. I love the part of the conversation between the young and the elder alien scientists. Looking forward to watching next episodes.
This was an excellent video, thank you! There certainly were many other stops which could have been made, but I get that run time is an issue. To me one of the more fascinating things to learn from presenters such as yourself was that it is believed that the earliest life's power source was not the sun, but hydrothermal vents in the ocean. Another good stop for our fictional alien visitors would have been our red planet. I'm not talking about Mars, but when life turned the ocean red by releasing oxygen, which reacted with iron hydroxide in the ocean filling it with fine particulate rust.
I absolutely love your channel and want to thank you for it! It’s truly awesome. I love space. I play star citizen and Kerbal a lot and when I’m at work I enjoy learning about space in depth so I appreciate your channel and what you do. Keep it up!
To my understanding there were two closely spaced Snowball Earths, and simple animals (like sponges) emerged between them and survived the second event.
Nice vid : ) I really like seeing visuals of what Earth might have been like in the past. I always remember this exhibit at the Denver Museum of Nature and Science where they have a movie on this exact topic. As a young child it always filled me with excitement at the idea that we humans are just the epilogue of a long and and difficult journey.
There were primitive animals like Sponges & Comb Jellies around as far back as 720mya, and may have played a major part (along with persistent vulcanism) in ending the cycle of ice ages (Snowball Earth) during the Cryogenian Era.
thank you for the word "vulcanism" when i was being schooled in the geologic, etc., sciences, that word was favored by far over volcanism which seems to be in vogue today.
These videos are brilliant for falling asleep to lol. I mean, they’re interesting/great entertainment when you have the mental energy, but when you don’t they are perfect for the old “fall asleep by trying not to” trick
It’s said that some dinosaurs evolved into birds but did they themselves evolve from a flying creature? Three things about birds and dinosaurs which may suggest this. One, birds and possibly dinosaurs have/had more efficient lungs over mammals meaning flight is easier. Two, birds and probably dinosaurs have less heavy but stronger bones meaning flight is easier. Three, birds and perhaps dinosaurs have/had smaller more efficient neurones meaning less weight.
I like this look of our prehistoric Earth through the eyes of alien visitors. This is how I views alien life in our galaxy. Too many people are caught up in the right now with wondering if life exists out there, and that since we aren't finding any evidence right now, that that means there probably isn't anything out there. Well, we've only been looking for roughly 50 years and have had signals leaving Earth for roughly 100 years. That's literally nothing in the scale of time of the galaxy. This planet could have easily been visited multiple times hundreds of millions of years ago, and there's no way we could possibly know that. That civilization of aliens could easily have gone extinct 50 million years ago. Earth could have been a vacation spot for them, again we would never know. All feasible evidence they could have left behind is gone through weather, erosion, and plate tectonics. At the same time, space is huge and planets are tiny by comparison. There could be ten other star faring civilizations within our galaxy right now, and none of them would even be able to know about each other. Our signals now encompass a roughly 100 light year radius sphere around our sun. There are anywhere between 10-60 thousand stars in that bubble versus roughly 100 billion stars in our galaxy. The probability of intelligent life being within that bubble to hear us compared to outside that bubble is so incredibly small.
The thought of meeting with peaceful lifeforms of another system is just... **goosebumps** thrilling to imagine. I'd be terrified for them if they were to show up now, though... The planet is not ready for something of *that* nature.
Most likely any meeting would result in one or the other species being eliminated. If a more advanced lifeform made it's way to Earth, they would be so far ahead of us that they may just look at us like annoying little bugs.
Not necessarily. You underestimate the war of small fleet against the entire planet. The only thing I can think of is some heavy planet bombardment from the orbit or even redirecting an asteroid to collide with Earth. It would be very hard to engage them in space, much easier on the ground or in the air. Imagine the entire planet switching to war time production and focusing on a single goal.
@@larrybud -eww, this planet got humans! disgusting! -don't worry honey, give me the bug spray and I'll get it clean for you. **ffsssshhhhhhhh** 😂 yeah, it would be something like that, probably
The planet is ready. It's the would-be rulers of "governments" who would fear the loss of their perceived power and want war... with US, the People forced to do the actual fighting, of course.
@@pavel9652 Why do people always go the extreme route? It baffles my mind. Why do you think of war? Why does everybody jump right to *"extermination?"*
I like to imagine those increased tidal forces as a veritable wall of water like constant tsunami, a massive tidal wave the moon drags across the surface of the primordial ocean. Inundating coastal regions, estuaries, and flood plains daily!
@@KutWrite Yes indeed! I wonder what it would feel like? If one could actually feel the moon pass by so close? I wonder how that affected biological life? I imagine the blue greens had to create those stone and glue structures to keep from being swept away by it.
Alex, you have a humble, intelligent and engaging way of communicating science. Your visual content is possibly the best on TH-cam, and I watch a lot of space and paleontological videos. I would be especially interested in what you can find regarding the evidence for the proto-planet and Earth collision that created the Moon. I have heard of this many times but have never heard the explanation for this hypothesis. I'm sure you would do an amazing job of it. In fact, you may have already covered it, so a link would be much appreciated if that is the case. Thank you, Sir.
Fascinating video, as always! Felt like visiting a museum for a very brief period of time. With that said, I think that we'll be extinct long before our alien scientists come and visit us again. We're wrecking havoc on that beautiful world in which we evolved, and we're our own Great Filter.
It would be great to learn more about scientifically simulated futures. Maybe even a series on what the world will look like if we continue as is, or if we dramatically change our ways in order to try to keep the Earth habitable for life as we know it. As we all know, no matter what we do, the Earth will survive, but will we?
There was a documentary on The Discovery Channel a while back called "The Future is Wild" that explored how animals in the future might evolve to adapt to the changing climate caused by tectonic movement.
Thank you for this episode. I’m simply a layperson who enjoys astronomy and geology, but I’m still a bit surprised I didn’t know of this, but presenting the water formation theory on meteors at 4:00 was a ‘Ohhh, that’s a great notion’ moment. I thought the water on earth coming from meteors made sense, but I just never understood how meteors could be composed of it. It felt like kicking the can down the street thinking meteors were just a convenient crutch to explain the appearance of anything on the earth, but the hydrogen ions combining w oxides on the space rocks is so logical and perfectly plausible.
6:50 Just before the great oxidation the oceans were green from the various iron compounds dissolved in the water. When oxygen was formed the iron reacted forming iron oxide (rust) which was eventually buried beneath the ground. This is what we mine today to produce iron.
This is the only kind of history that I've ever been interested in.i love learning about the difference time periods of earth and what might have lived back then
Yes! Honestly, I love your videos and would like more of anything. Yet, sure! How about more on our planet's geologic mysteries ? With perhaps, including as seen by our alien friends? 👽 I really enjoyed the part with your alien narration!
Janet Janet Janet, how did you learn something from imagination and speculation? The narrator even says it is. You were entertained, but you gained no knowledge.
The camera men go unmentioned because they send disabled kids from India to do it and most don’t make it back they just send the footage in the Time Machine and the keep filming… if they say their names then they have to say they have died so they say nothing…they are good at it though they get amazing footage
In 5th grade i had a friend who made a story about pangea getting into a fight and breaking up 😂 she is super smart and it was so good the principal read it to the whole school
This was so enjoyable, thank you. If only school taught this way when I grew up. I'd actually love it. Keep kids home with family and show these types of videos.
The sun was not as hot, but I don't know how much that affected it's brightness. I would think a larger moon would mean more light reflected, yes. I wonder of anybody has tried to calculate that
Im no scientist but often find myself watching these videos to remind nyself im nothing great, only a mere grain of dust if even that! compared to the earth, the universe and beyond. This keeps me humble and greatful too
Brilliant. Just brilliant! I know its partly speculation but i am interested to know more about life, early creatures and conditions befor dinosaurs. Thanks for such a well thought out and presented channel.
Well, the dinosaurs were created on Day 6, birds and fish on Day 5, and plants on Day 3. I sure hope that answers the question posed by the title of this video.
Great demonstration on how our planet was formed. I always enjoy watching these videos. But the only thing I never knew was that the moon we know today was formed by a collision. You learn something everyday.
Very nice video. To the point, informative, well narrated, and visually pleasing, and very importantly: acknowledge the fact that everything is not for sure or fact, but a best guess of what happened, based on known info, subject to change or modification. Documentaries must be hones about that.
Paleontologists now agree that all of the raptor type dinosaurs were completly covered in feathers and looked more like a flightless bird than the reptiles they make them out to be.
Facinating when you think about what is an an enormous amount of time to us....say 500 years... think of all the generations that have come and gone before us the last 500 years. They are long forgotten... All the things and events that have taken place in our history, yet that is just a blink the eye in just one of these several time period's that was discussed.
5:32 when he says the Moon will STOP drifting away, kinda false, the moon WILL stop orbiting the earth, but it'll fly off into space, important fact missed...
I can ask my mother-in-law. She was here back then. Hang on...

Yeah, the more I learn the more I realize we are utterly meaningless as individuals but have a massive impact as a species, and the things we do that ruin the planet for our own convenience are super selfish and we would have no need to explore space for another rock to live on, if we just took care of our own and were responsibly intelligent rather than recklessly intelligent
A nanospeck on a nanospeck is pretty solid, but realistically we are probably a nanospeck on that second nanospeck. Haha. It's comical that we as a species think we are special enough that anyone, if they existed in the cosmos somewhere, would even look at us as intelligent. We're just less hairy apes when it comes down to an outside perspective, were one to exist.
@@goosenotmaverick1156if we are meaningless as individuals who care what we do!!! Why should we have morals if we are meaningless!! We should just do whatever makes us happy since there’s nothing left after we die! The utter ridiculousness of evolution!

@@mykehog6646 sounds like you read to many fairy tales. I think you are in need of a bedtime!! Also sounds to me like you have some knowledge of the Bible, and you choose to reject it and choose to believe what these people tell you happen with no evidence no proof just theories of things when no one was around to record anything, oh yeah wait we still hadn’t evolved enough to keep records that’s why there’s no record of what happened right!!😂
From the end of the dinosaur extinction some 64 million years ago and the beginning of "humans" some 5 to 7 million years ago, what did our Earth look like to our alien visitors? Great video as always.
There’s typically a new government every 1 million or so years. Right now The Domain expeditionary force own the earth. Like the 1947 Roswell crash.
65 million years ago*

Grass grew and changed everything.
I believe humans were here during dinosaurs reign there's proof of ITIN Utah by foot prints together
The Devonian and the Cambrian animations always brings me back to my Child Craft encyclopedias in the 70s. The pictures in the book were like animations within my mind, and definitely patterned some neural networks in there.
I still have my set, lol.
I had those too, except I'm a 90s kid lol
I wish I still had them
Bruh it's weird to think of a world before Mass Effect
What about the Mushroom Era, where Lichens/Mosses, and mushrooms, maybe some ferns were the only "plants". Before more complex plants/trees even existed? They broke down the barren volcanic rock into something plants/Ferns could root in, and then the plants dying created the soil.
What an amazing video journey! Thank you Alex.
Thanks!
Wow thank you so much!
🌹
Wonderful video combining geography, geology, astronomy and paleontology! It would be awesome if you did more videos of Earth's evolution.
Well aren't you just a charmer
🌹
By the time this planet becomes uninhabitable again (which it will), if you measure the Earth's whole lifespan as a 12 hour clock face, life would only have been possible for 4 minutes.
This isn’t true….
The oldest known fossils are 3.7 billion years old and models show the earth should remain habitable to life for anywhere between 1 and 2 billion years more. Meaning at worst the earth over its entire lifespan would of held life for 4.7 billion years. The earth is expected to be destroyed in about 7.59 billion years and has been around for about 4.6. So that is a expected 12.29 billion year life span where life was possible for at least 4.7 billion years of it.
Which means on a 12 hour clock face, that’s over 4 hours. No idea how you reached your claim.
Really enjoyed that.
Just returned from the dinosaur trail in Western Qld when much of Australia was under 60m of water around 100 million years ago. Fascinating.
This is an awesome video idea, i always wondered about this, you'd read about it in text books but visually it's far more captivating.
Yes, please more of videos like this one, i enjoyed the work on graphics, wish this video was longer than 16 minutes.
It is amazing how, as each year goes by, the scientists discover and reveal new facts about Earth's history. Whilst many things are debated, as they should be, intelligent extrapolation leads us ever nearer to clarity about our past. Hopefully erasing superstitious nonsense and folk tales along the way. Science rules. Something we need to keep reminding ourselves of in these insane times.
Yes... and debunk previously accepted "facts."
Unfortunately, politics rules over science. That's how we can have this wonderful video which accurately depicts how Earth's climate has changed throughout its entire history, and yet, you'll still get people believing that man is causing a climate crisis, and they'll say that 97% of scientists agree without even thinking about who funds those 97% of scientists who are agreeing, or that it's usually the few scientists who discover the truth and have a hard time getting people to believe them (like Galileo). So yeah, money rules... politics rules... science is somewhere on the bottom. Right now, science is nothing more than a tool to spread mass propaganda.
🌹
@@G360LIVE You are right on the
money. Which is what this whole nonsense is about.🥴🥴
This could be a whole series, great video
He is welcome to try, but others have already done it.
🌹
People just really throw around “theory” as if “hypothesis” isn’t a perfectly good and way more accurate word.
You always have amazing, informative videos, but this one has to rank among the best ones.
Astrum has quickly become one of my all time favorites on TH-cam. I want more!
Thank you. Very enjoyable. I love the part of the conversation between the young and the elder alien scientists. Looking forward to watching next episodes.
This was an excellent video, thank you! There certainly were many other stops which could have been made, but I get that run time is an issue.
To me one of the more fascinating things to learn from presenters such as yourself was that it is believed that the earliest life's power source was not the sun, but hydrothermal vents in the ocean.
Another good stop for our fictional alien visitors would have been our red planet. I'm not talking about Mars, but when life turned the ocean red by releasing oxygen, which reacted with iron hydroxide in the ocean filling it with fine particulate rust.
Good overview of how Earth changed over the millennia.
the writing of the segment about the two alien scientists arguing is simply genius.
I absolutely love your channel and want to thank you for it! It’s truly awesome. I love space. I play star citizen and Kerbal a lot and when I’m at work I enjoy learning about space in depth so I appreciate your channel and what you do. Keep it up!
We definitely need a part 2 of this one.. possibly a mini series??
This was the most interesting video I have seen in ages. Thank you! I'd love to see more of this kind of videos!
@Hello there, how are you doing this blessed day?
To my understanding there were two closely spaced Snowball Earths, and simple animals (like sponges) emerged between them and survived the second event.
Nice vid : ) I really like seeing visuals of what Earth might have been like in the past. I always remember this exhibit at the Denver Museum of Nature and Science where they have a movie on this exact topic. As a young child it always filled me with excitement at the idea that we humans are just the epilogue of a long and and difficult journey.
And what we are is a product of everything that has gone before, which makes it even more fascinating.
🌹
Please don't come now aliens. There's no intelligent life here at the moment.
They lock their spaceship doors any time they drive by Earth. 😉
All shore leave is cancelled.
This was very interesting. Very informative, and well put together.
This guy put me to sleep. About five minutes into the video, and I'm about ready for a nap.
What an awesome episode. Well scripted and expert level visuals.
That was soo cool to see you put Earth’s history into the perspective of Aliens! I LOVE your channel so much!!!
I am an alien. An illegal one. 😜😜
There were primitive animals like Sponges & Comb Jellies around as far back as 720mya, and may have played a major part (along with persistent vulcanism) in ending the cycle of ice ages (Snowball Earth) during the Cryogenian Era.
thank you for the word "vulcanism" when i was being schooled in the geologic, etc., sciences, that word was favored by far over volcanism which seems to be in vogue today.
These videos are brilliant for falling asleep to lol. I mean, they’re interesting/great entertainment when you have the mental energy, but when you don’t they are perfect for the old “fall asleep by trying not to” trick
It’s said that some dinosaurs evolved into birds but did they themselves evolve from a flying creature? Three things about birds and dinosaurs which may suggest this. One, birds and possibly dinosaurs have/had more efficient lungs over mammals meaning flight is easier. Two, birds and probably dinosaurs have less heavy but stronger bones meaning flight is easier. Three, birds and perhaps dinosaurs have/had smaller more efficient neurones meaning less weight.
I like this look of our prehistoric Earth through the eyes of alien visitors. This is how I views alien life in our galaxy. Too many people are caught up in the right now with wondering if life exists out there, and that since we aren't finding any evidence right now, that that means there probably isn't anything out there. Well, we've only been looking for roughly 50 years and have had signals leaving Earth for roughly 100 years. That's literally nothing in the scale of time of the galaxy. This planet could have easily been visited multiple times hundreds of millions of years ago, and there's no way we could possibly know that. That civilization of aliens could easily have gone extinct 50 million years ago. Earth could have been a vacation spot for them, again we would never know. All feasible evidence they could have left behind is gone through weather, erosion, and plate tectonics. At the same time, space is huge and planets are tiny by comparison. There could be ten other star faring civilizations within our galaxy right now, and none of them would even be able to know about each other. Our signals now encompass a roughly 100 light year radius sphere around our sun. There are anywhere between 10-60 thousand stars in that bubble versus roughly 100 billion stars in our galaxy. The probability of intelligent life being within that bubble to hear us compared to outside that bubble is so incredibly small.
Yes, please. More videos like this one. Cheers!
The thought of meeting with peaceful lifeforms of another system is just... **goosebumps** thrilling to imagine.
I'd be terrified for them if they were to show up now, though... The planet is not ready for something of *that* nature.
Most likely any meeting would result in one or the other species being eliminated. If a more advanced lifeform made it's way to Earth, they would be so far ahead of us that they may just look at us like annoying little bugs.
Not necessarily. You underestimate the war of small fleet against the entire planet. The only thing I can think of is some heavy planet bombardment from the orbit or even redirecting an asteroid to collide with Earth. It would be very hard to engage them in space, much easier on the ground or in the air. Imagine the entire planet switching to war time production and focusing on a single goal.
@@larrybud -eww, this planet got humans! disgusting! -don't worry honey, give me the bug spray and I'll get it clean for you. **ffsssshhhhhhhh** 😂 yeah, it would be something like that, probably
The planet is ready. It's the would-be rulers of "governments" who would fear the loss of their perceived power and want war... with US, the People forced to do the actual fighting, of course.
@@pavel9652 Why do people always go the extreme route?
It baffles my mind. Why do you think of war? Why does everybody jump right to *"extermination?"*
What freedom and health the Earth must have felt before Man came along to poison and maim her.
Please do more Alex. This was excellent.
I like to imagine those increased tidal forces as a veritable wall of water like constant tsunami, a massive tidal wave the moon drags across the surface of the primordial ocean. Inundating coastal regions, estuaries, and flood plains daily!
Which is what inevitably slowed down the Earth.
Rippling and heating the Earth's crust, too.
@@KutWrite Yes indeed! I wonder what it would feel like? If one could actually feel the moon pass by so close? I wonder how that affected biological life? I imagine the blue greens had to create those stone and glue structures to keep from being swept away by it.
🌹
i’d definitely be interested in more of this sort of thing. i really enjoyed this video. nice work!
Alex, you have a humble, intelligent and engaging way of communicating science. Your visual content is possibly the best on TH-cam, and I watch a lot of space and paleontological videos. I would be especially interested in what you can find regarding the evidence for the proto-planet and Earth collision that created the Moon. I have heard of this many times but have never heard the explanation for this hypothesis. I'm sure you would do an amazing job of it. In fact, you may have already covered it, so a link would be much appreciated if that is the case. Thank you, Sir.
Thank you so much for this beautiful video. 📹
Fascinating video, as always! Felt like visiting a museum for a very brief period of time. With that said, I think that we'll be extinct long before our alien scientists come and visit us again. We're wrecking havoc on that beautiful world in which we evolved, and we're our own Great Filter.
Thank you Alex. Another engaging, entertaining, and visually stunning video. More!!!
It would be great to learn more about scientifically simulated futures. Maybe even a series on what the world will look like if we continue as is, or if we dramatically change our ways in order to try to keep the Earth habitable for life as we know it. As we all know, no matter what we do, the Earth will survive, but will we?
Great ideas.
There was a documentary on The Discovery Channel a while back called "The Future is Wild" that explored how animals in the future might evolve to adapt to the changing climate caused by tectonic movement.
@@ShawnRavenfire Thank you, however that's only helpful if you have the discovery channel... lol Seriously though, thank you!
@@R0bobb1e I think it's also available on TH-cam.
@@ShawnRavenfire Oh, sweet! I'll see if I can find it. Would still be nice if Alex made something... :)
Thank you for this episode. I’m simply a layperson who enjoys astronomy and geology, but I’m still a bit surprised I didn’t know of this, but presenting the water formation theory on meteors at 4:00 was a ‘Ohhh, that’s a great notion’ moment.
I thought the water on earth coming from meteors made sense, but I just never understood how meteors could be composed of it. It felt like kicking the can down the street thinking meteors were just a convenient crutch to explain the appearance of anything on the earth, but the hydrogen ions combining w oxides on the space rocks is so logical and perfectly plausible.
At this volume though? I don't know...
The first rains lasted for millions of year ❤
6:50 Just before the great oxidation the oceans were green from the various iron compounds dissolved in the water. When oxygen was formed the iron reacted forming iron oxide (rust) which was eventually buried beneath the ground. This is what we mine today to produce iron.
This is the only kind of history that I've ever been interested in.i love learning about the difference time periods of earth and what might have lived back then
Yes! Honestly, I love your videos and would like more of anything. Yet, sure! How about more on our planet's geologic mysteries ? With perhaps, including as seen by our alien friends? 👽 I really enjoyed the part with your alien narration!
I loved this video and would love to see more like it. I learned at least 3 new things and I am especially fascinated by the early plant life!
@Hello there, how are you doing this blessed day?
Janet Janet Janet, how did you learn something from imagination and speculation? The narrator even says it is. You were entertained, but you gained no knowledge.
The camera man deserves an award.
The camera men go unmentioned because they send disabled kids from India to do it and most don’t make it back they just send the footage in the Time Machine and the keep filming… if they say their names then they have to say they have died so they say nothing…they are good at it though they get amazing footage
Real captions that aren’t auto generated. Very legit. Thank you.
needs a new title--no creatures until almost halfway through, and no "bizarre" ones until after 3/4 through
"Life finds a way."
Yep he said it first and best and it will forever be true
In 5th grade i had a friend who made a story about pangea getting into a fight and breaking up 😂 she is super smart and it was so good the principal read it to the whole school
I would love to hear you cover strange/rare planets outside the solar system
I would love to hear Alex upload one hour of total gibberish.
🌹
When we get there then we can discuss them.
Until then .................
This was so enjoyable, thank you. If only school taught this way when I grew up. I'd actually love it. Keep kids home with family and show these types of videos.
NO, teach your children TRUTH from God's Word, not this total made up rubbish!
Oh yeah I would love to here more ❤ this was unbelievably beautiful and very well edited love the way you tell earths stories it’s always fascinating!
I'm curious how bright were the nights 4.5 bln yrs ago? Moon was much closer back then, so it must have been as bright as in the dusk, right?
The sun was not as hot, but I don't know how much that affected it's brightness. I would think a larger moon would mean more light reflected, yes. I wonder of anybody has tried to calculate that
@@jockyoung4491 thanks for reply
Except, closer to Earth it would likely have more of Earth's shadow on it, so it wouldn't be fully illuminated.
🌹
I’m at the 12 minute mark and still have yet to see a single creature in this video. Might wanna re think the title…
I can't get enough of your vids. I watch them before bed almost everyday.
You have the best narrating voice in the world it pulls me in and it makes me more interested in what you’re talking about! Lol
I love the way you go about this from an alien's perspective.
Very interesting and, as always, informative! Thanks
Im no scientist but often find myself watching these videos to remind nyself im nothing great, only a mere grain of dust if even that! compared to the earth, the universe and beyond. This keeps me humble and greatful too
Brilliant. Just brilliant! I know its partly speculation but i am interested to know more about life, early creatures and conditions befor dinosaurs. Thanks for such a well thought out and presented channel.
Well, the dinosaurs were created on Day 6, birds and fish on Day 5, and plants on Day 3. I sure hope that answers the question posed by the title of this video.
I for one would enjoy hearing more about earth's past!
Great demonstration on how our planet was formed. I always enjoy watching these videos. But the only thing I never knew was that the moon we know today was formed by a collision. You learn something everyday.
Absolutely stunning, these animations are amazing.
Very nice video. To the point, informative, well narrated, and visually pleasing, and very importantly: acknowledge the fact that everything is not for sure or fact, but a best guess of what happened, based on known info, subject to change or modification. Documentaries must be hones about that.
Oh yeah, I am really interested in viewing any of your well-documented library of new videos, well done.📺
Starting my BINGE of the CHANNEL before it is GONE. ❤️
Wow ! What a brilliant video ! Including the presentation. I kept thinking to myself 'I must subscribe.' But I see I already have !!
If the moon was formed by a planet crashing into the earth, tell me why we don’t have a ring ?
A recent study has found that the day length was stable around 19 hours for about a billion years before starting to lengthen again.
Paleontologists now agree that all of the raptor type dinosaurs were completly covered in feathers and looked more like a flightless bird than the reptiles they make them out to be.
First time your channel showed up in my feed - love it! Subscribed.
Facinating when you think about what is an an enormous amount of time to us....say 500 years... think of all the generations that have come and gone before us the last 500 years. They are long forgotten... All the things and events that have taken place in our history, yet that is just a blink the eye in just one of these several time period's that was discussed.
5:32 when he says the Moon will STOP drifting away, kinda false, the moon WILL stop orbiting the earth, but it'll fly off into space, important fact missed...
