PZ's better answer

On occasion, I've said that if I ever met God I'd slap his face hard. What a monstrous creature he would have to be (if he existed, which he doesn't), creating pain in the world and killing children with gruesome diseases. That sort of being deserves nothing less than a slap in the face.

PZ Myers answers the same question in a more thorough manner. I must say, I like his answer better.
