Atheists/agnostics and believers - what would make you change your mind?

Oh, someone already said Babelfish before me. But then again, D.N.A. already wrote that.

I change my mind. I’ll believe when I have been touched by His Noodle Appendage, the FSM.

Miracles would not. Miracles are by defenition exceptions to what is possible and impossible. If god created the universe then why would he break his own rules??

But seriously, what would convince me was a decent theory that does not look like men making something up to feel better about. All the little errors seem to reveal that it’s really man who creates god in his own image.
It all reminds me very much of the experiment once conducted by Skinner, “Superstition in pigeons”. Skinner is the inventor of animal testing (only behavioural AFAIK) where they are in a box and get rewards (food) for certain kinds of behaviour.
Once, pigeons simply got food with a certain interval no matter what they did. Pigeons in this test develloped superstitions of silly actions they had to perform in order to receive the reward. That begs the question: how do we know we’re not doing exactly the same but with bigger stakes?
