    If we lived light years from Earth, how would we know there’s life here? Let’s take a look at the search for extraterrestrial life on habitable exoplanets, and discover what biosignatures would show someone else that we’re here.

      @@cxx23 Ehhh... that is true, in a manner, but, while we don't know what alien life will be like, we can take some educated guesses. For example, even the most basic life needs incredibly complex chemistry, so it would need to be based on an element that can make 4 bonds. Any less than that, & even the simplest self-replicators couldn't exist. Practically speaking, this means carbon, or maaayyybe silicon. Given carbon's relative abundance as compared to silicon, carbon is a solid bet.
      The lighter elements are far more common than heavier ones, so it's not unreasonable to think that life on other planets would be working with pretty similar ingredients -- Hydrogen, Oxygen, etc -- simply because that is what they have access to. These also have pretty interesting chemical properties that would be useful for life to take advantage of, & given how common they are, it would be odd if evolution didn't drive life to use them.
      We can also look at convergent evolution here on earth to see how easily life can evolve certain traits. This doesn't really help much with the very very early stages, since we don't know much about how life started, but we could take some educated guesses about more complex life. For example, there will probably be cells with cell walls, life would probably eventually figure out some form of photosynthesis, & if there are complex, mobile, multicellular organisms, they'd probably develop some sort of blood.
      Notably, this doesn't actually tell us *how* it would do such things, only that it probably would. For example, the odds of finding photosynthesis elsewhere may be fairly high, but the odds of that photosynthesis using chlorophyll would be pretty low, rendering the red light drop technique mentioned in the video useless.
      One of the reasons liquid water is such a big deal is life would likely only develop in some sort of liquid. Very very early replicators wouldn't be able to afford spending energy doing basically anything, & even once they develop a little, they're still going to need all the energy savings they could get. Diffusion would be the only practical zero-energy way of getting nutrients & removing waste products, & that would require being in a liquid. If that liquid is made out of some of the same basic elements you need to build yourself, all the better.
      It may seem self-centered to imply that our form of life is the only that could exist, but at the end of they day, anyone else out there is working with all the same chemistry & physics as us, & are probably facing a lot of the same challenges as life here. From that perspective, it's not so crazy to think whatever's out there would probably be reasonably similar to us.
      All this comes with a huge asterisk, of course. Our knowledge of chemistry is very very good, but not perfect, so it very well could be that under strange conditions (high pressure, weird atmospheres, extreme temperatures) things react differently, making life possible where we wouldn't expect. All this is also, of course, speculation. I have to throw in a bunch of "probably"s & "might"s, since we won't actually be able to say anything more concrete until we actually do find life.

    Joe, So no one will ever read this, because my comment is more than 2 years after the original video. But I've spent about 6 hours now looking at your videos, and I can't express how much I appreciate them -- and I'm a writer! I've always been interested in science, but my career took me in different directions, primarily into law. Had I been a bit better with calculus, I suspect I would have ended up in engineering mechanics, and maybe into chaos theory. Thanks for filling me in on science. With respect to this particular video, it's amazing to think that between when I went to high school -- with no exoplanets known -- and 2019 -- when you did the video -- we've discovered more than 2,000 planets outside our solar system. And that life exists *everywhere* on our planet (although I'm not sure I learned that from you). I hope we get some confirmation of life elsewhere before I die.

    The basic problem is that we are trying to define life in general based on a sample size of one. We don't really have a definition of alien life. For instance, who said liquid water is necessary for life? It is on Earth (mostly), but who said life evolving elsewhere would also need it? We don't even know how to ask that question properly, because we don't have a concept of "life in general"; only of "life on Earth".

      Simple life is, I would say, nearly guaranteed, but intelligent life is probably quite rare. Consider that life has been on Earth for some 4 billion years, multicellular life for only 1-2 billion years, and remotely intelligent life for a few hundred million years. Earth only HAS another billion years before our oceans start to boil. I imagine many, many potentially intelligent species will simply evolve too late to escape their own homeworld, assuming our Earth and Sun are typical of systems with life.

    We’re looking for anything and everything so it’s possible that life is out there somewhere. I’m not going to knock it because you just have to believe. It would be amazing to see life some place else.
