The problem here is that most people, regardless of their individual beliefs, look down on those who don't believe the same. I'm not exactly an atheist, basically I don't subscribe to a particular faith or a religion but I still have respect for those that do. In order to do that you have to have faith in what you believe in and that in itself is impressive to me. there is no definitive proof either way and i just don't really have faith in the "invisible man in the sky" nor do I have any faith in the claim that there is no such "man in the sky" simply because I do not know.
