Just to clarify, I am NOT certain that God does not exist. As Maher has said in multiple interviews, I don't even consider myself an atheist because it mirrors the same certainty that many Christians have. The common ground I find is that neither scenario can be proven, and for that reason I find it unreasonable to say that either is a certainty. I never say there definitely is not a god, if I did, I would be the same idiot as someone saying there definitely is a god. And when I talk of god, I'm not even speaking of the christian god, because if there is some sort of higher power, I definitely don't think it's the god that Christians worship, and the Jews, Muslims and all other religions for that matter.
