Ricky Gervais: from Xian to atheist in 1 question

Ricky Gervais: My Argument With God

... my big brother Bob asked, "Why do you believe in God?" Just a simple question. But my mum panicked. "Bob," she said, in a tone that I knew meant "shut up." Why was that a bad thing to ask? If there was a God and my faith was strong, it didn't matter what people said.

Oh... hang on. There is no God. He knows it, and she knows it deep down. It was as simple as that. I started thinking about it and asking more questions, and within an hour, I was an atheist.
