Well, the Bible describes God creating man and woman. Either it's true as written or the Bible is just another worthless book. But is can't be both.
If I rejected everything in every book I read based on whether or not one particular something in it was literally true or not, I'd never believe anything in any book I read. Why do you take this position?
Because I take the Bible literally as I have no reason not to. If we descended from ape-like creatures and life began without any Creator, then there is no Creator and no God. Do you think "nature" created itself out of nothing?
