Atheism is a religion.
You don't have to "prove" god isn't behind evolution, just like you don't have to "prove" leprechaun's aren't behind it. Evolution works as described. If you want to insert an undetectable director into it, the burden of proof is on you. [from this post]
Apple salesman: My apples are better than your oranges.
Orange salesman: You're wrong. My oranges are tastier than your apples.
Apple salesman: How illogical! My apples are much more enjoyable than your oranges.
Orange salesman: Poppycock!
Shvek [member of the Unified Atheist League]: Our answer to the Great Question is the only logical one. Our Science is great. Let us not forget the great Richard Dawkins who finally freed the world of religion long ago. Dawkins knew that logic and reason were the way of the future. But it wasn't until he met his beautiful wife that he learned using logic and reason isn't enough. You have to be a dick to everyone who doesn't think like you. Prepare all the troops! We will level the United Atheist Alliance to the ground!
