" If life - and by extension, humanity - evolved, then the events in Genesis did not actually happen, and by extension, the historicity of the Bible - and ultimately, the legitimacy of Christianity itself - is called into question."
As someone has pointed out, Religions need to create "Sin" in order to SELL you the way to Salvation from their invented "Sin".
I remember a conversation I had with an Elder a few months back, we, as two Old Farts were comparing ailments, and he said a lot of it was genetic and all "Adam's fault", I quickly replied " Well, you can go back further in time than that, a number of things we suffer from come from Neanderthals, and they died out 30,000 years ago".
The silence would have been total after my, not entirely accurate comment, except I could hear the gears turning in his brain as he sought a reply.
