Your answer, is very telling.
Both fossil records and DNA analyses suggest it does.Your answer makes my case. Your are not sure or you would simply say. YES. But you know you do not KNOW it is TRUE that Darwinian evolution accounts for diversity of life on earth. It may. It may not. But when you deny certitude you open the door to other possibilities. Either diversity of came from undirected chaos or it came from intelligence. Even your referential expert Fred Hoyle thought it might come from intelligence via panspermia. (He later recanted of course). So, if you do not know it is true you must at least admit to the possibility of metaphysical naturalism.
You and I seem to have nothing else to say to each other. Thank you for your correspondence.
Since your claim of “diatribe” is yet another false accusation, it says nothing about me, but reflects poorly on you.
And I think I’ve explained already that “certitude” is not what science is all about.
In science, no theory outside mathematics is ever “proved”, but only “confirmed”, and that only by passing tests intended to DISprove it.
And once confirmed, a hypothesis is only tentatively accepted as “theory” until some new test falsifies it.
Point is: there’s no ontological or metaphysical certitude in science.
Those ideas are left for other branches of philosophy.
