Where did the universe come from: the Big Bang? Create something out of nothing? For us, this is all speculation. Historical assumptions and experiments have been unable to accurately tell where it came from. But human beings have never stopped pursuing "truth". Perhaps only humans will pursue the truth of such origins, while other animals and plants only survive in order to pass on the family lineage from generation to generation. As for the origin and meaning, because without the unique thoughts of humans, they will not realize what it is.
And the unique thoughts formed by human beings are just a splash in this long history. The "origin", world view, values, and outlook on life only exist in the space structure of the world that they think.
Perhaps there is higher intelligence and higher civilization, living hundreds of millions of light years away, in parallel time and space, these are unknown...
Purpose: Pursuing the origin
