As I've tried to argue before, faith and religion are two separate things. I may be an atheist and defend evolutionary theory, but I also have faith in something important. Religion just says we're all wrong, and is done with it... We all go to hell if we don't agree...
Maybe. I think faith in and of itself is a religion. Or at least it has a religious aspect. It is the belief in something for which there is no evidence.
Religion requires faith because face it, there ain't no evidence for a God. The modern theory of the creation of the Universe requires faith as well.
There actually is evidence to support the theory of evolution. It is limited, but it is there.
