Newton (centuries ago) has 3 laws of Motion: LAWS - I say again: L A W S, which are incontrovertible.
Darwin (more than a century ago) had a notion which is NOT a law of ANYTHING - meaning he was like my uncle who had a notion he could fly. Both of these dudes are DEAD! My uncle left a wife and four children. Darwin left confusion and hope amongst those who refute/doubt Creationism.
Whether it was a God, gods, cottage cheese or a yield sign everything on Earth was created. The purpose: I have not the foggiest! Dogma? I give it little credibility as it is the creation of man
