Responding to claims from fellow wrestler Teddy Hart that: "If God wants him to make it in the WWE, then he will... there is a reason God lets him do 30 foot moonsaults(A high-flying wrestler move that Hart had recently performed off the top of a steel cage.)."
Punk stated: "There is no god, and the cage wasn't 30 feet."
For proof of Punk's fame (Although his Atheism is not mentioned) here is his wikipedia page: [2] [[3]]
Here is where he mentions his Atheism. https://twitter.com/CMPunk/status/259553683803623424 It is worth mentioning that he was the reigning WWE Champ for 434 days.
