Richard Carrier on Bayes' Theorem. Before I watched this video, I couldn't say I liked this cat. After, he's a superhero. So sit down, shut up, watch this, and learn something. :D
If this guy knows what he's talking about, then there is no reason for any other religion than atheism. Those people who say atheism isn't a religion would sure sing a different tune if it were the only religion. So why don't we get together and make atheism the only religion first, and then there will be no reason to call ourselves atheists, and we can all got back to being human beings.
Sound like a plan?
