It's so funny that Aetheists and religious nuts are so against each other when really, they are saying the same thing.
Aetheists say that there is no God because they are so sure that there isn't that they're willing to take that leap of faith. They use just as much faith as someone who believes there is a God uses. Yet they seem to think somehow they are above those who believe in God. An interesting use of circular reasoning, if you ask me.
This is the problem with human arrogance. I personally am agnostic. For those of you who don't know, gnosis is the Greek root for "knowledge," and a implies a negation. So therefore, I do not claim to have the Truth as do the arrogant followers of aethiesm and religion. I actually got into a really big argument with an aethiest once because I said that I could turn any aethiest into an agnostic. They were offended, but after a few hours they realized that it really is impossible to truly know whether or not God exists. Saying that God doesn't exist is just as big a leap of faith as saying that God does exist.
