“You can't prove that something doesn't exist. You can only prove that something does exist.”

“I mean, you could claim that anything's real if the only basis for believing in it is that nobody's proved it doesn't exist!”

“I’d learned a long time ago that you can’t prove a negative. You can prove that you did something, but it’s the devil to prove you didn’t do something.”

“I show you doubt, to prove that faith exists.”

“My most recent faith struggle is not one of intellect. I don’t really do that anymore. Sooner or later you just figure out there are some guys who don’t believe in God and they can prove He doesn't exist, and there are some other guys who do believe in God and they can prove He does exist, and the argument stopped being about God a long time ago and now it’s about who is smarter, and honestly I don’t care.”

“It has been proved that the land can exist without the country - and be better for it; it has not been proved that the country can live without the land.”
