Yes, but it is entirely consistent for a snake handler to think that handled snakes not biting is very strong evidence for the existence of a Christian god while also thinking that handled snakes biting is very weak evidence against the existence of a Christian god, weak enough not to significantly dent their faith. So Maher’s argument as stated doesn’t work. “Doing the math” here might just mean very very slightly reducing your credence in God’s existence.
