How to know Allah through the earth and the heavens

The evidence of the creatures:
The second of these evidences is the evidence of the creatures, for they are, by their number, evidence of the proof of their Creator, the Most High, the Most Great. In everything that Allah created in the heavens and the earth, there are clear signs that burn every doubt, silence every disbeliever, and force every stubborn and obstinate person, because they include testimony to Allah Lordship and Divinity over all creation.
These creatures, despite their greatness and perfection, were not created from nothing, just as they did not create themselves, and this is what is established by nature and is known by necessity and intuition. So, nothing remains except that they were created by the decree of the Almighty, the All-Knowing, who created and proportioned and who determined and guided.
And the proof of the Creator in the Qur’an by the same verses that knowledge of them necessitates knowledge of Him, just as knowledge of the ray necessitates knowledge of the sun without needing analogy or anything else.
Allah Almighty said:
( أَمْ خُلِقُوا مِنْ غَيْرِ شَيْءٍ أَمْ هُمُ الْخَلِقُونَ ) (At-Tur: 35)
“Or were they created by nothing, or were they the creators?” .
