Kurt Godel sent in a 1972 letter to Hao Wang, here what Godel wrote: here
I believe that mechanism in biology is a prejudice of our time which will be disproved. In this case, one disproof, in my opinion, will consist in a mathematical theorem to the effect that the formation within geological time of a human body by the laws of physics (or any other laws of similar nature), starting from a random distribution of the elementary particles and the field, is as unlikely as the separation by chance of the atmosphere into its components.
I want someone to explain it in modern times. For example, it looks that Godel doesn't believe in evolution, so he states that the reason may come from logical argument and moreover if there exist a counterexample that evolution is wrong, then he states the following which I don't understand: "the effect that the formation within geological time of a human body by the laws of physics is as unlikely as the separation by chance of the atmosphere into its components".
Does "geological time of a human body" mean "average age of human"?
