Actually, OP's point about evolution being the creation myth of the atheists has a solid basis.
Only to someone who doesn't know myth from scientific theory. I guess that would be you, since you seem to think Genesis is a scientific account.
Since the theory of evolution does not deal with "creation" (in the sense a creation story does) and is not a myth, it is not a "creation myth." If you can support your assertion further, though, I will consider it.
