I will prove to you that God exists

The reason atheists are such a minority is because you sell a fish story few believe.

The actual reason is most people are not rational in their beliefs

I once debated a creationist who insisted he could disprove evolution, I shan't name him, as he has popped up here years later. He insisted "most people think rationally". I asked him why if that were true, we bothered creating a method of reasoning that adheres to strict principles of validation, in order to quickly identify and discard irrational arguments. In the end I had to explain I was talking about logic, the silence was almost painful.
