I don't believe in anything. Yes, I fall into more of the agnostic atheist category - maybe a supreme being exists. I don't think one does, but hey I may be wrong.
But if one exists, its definitely unknown to us and is not any of the gods that I've heard of. I reject the idea of god as we humans understand and that earthly religions preach of. That makes me atheist. It's such a broad label - but that's basically what it is, a label. Not a religion, not a belief.
