What does evolution have to do with atheism? Seriously?
Atheism is defined as the absence of belief in deities. The absence of such belief isn't determined by acceptance of evolution; after all, the greek epicureans knew nothing about darwinian evolution and rejected the existence of gods, all the while there are respected evolutionists who accept the existence of the Christian god. However, in cases like mine, I can see how the evolution theory, if taken to its last consequences, lends to a disbelief in deities.
I'm not discussing here how life came to exist in the first place. The problem of sexual reproduction is central to the development of life and it ties inextricably with evolution. And that's where I find the evolutionary theory is seriously lacking an explanation the definitively rules out a supernatural / intelligent intervention.
Although I'm agnostic, I would rather be an atheist. Seriously. Being an agnostic is awkward because, not being sure of God's inexistence, I think that if God exists he/she is a bastard and not someone I would like to have interactions with or have my future dependent on. I would rather have no belief at all and that would be much better.
