The theory of evolution does not address the issue of creation. So how does it "reject" the Bible's assertion that God created mankind and all life on earth"?
Darwin posited that man descended from apes, that he was not created specifically by God. All evolutionists believe that else they are not evolutionists. As to all life, while not specifically stated, you will see that the evolutionists (and only the evolutionists) are on the side of abiogenesis (that life was created accidentally from inert matter) and try to prove it by numerous contortions and totally baseless assumptions. You will also note on these threads (as well as on most of the evolutionist literature) a profound hatred for religion and for Christianity in particular.
