That's hilarious. You repeat yourself and conclude that I'm on the hook to prove you.
You can repeat your own tautologies all day long bunky.
And as far as "what came before", the answer of "the tooth fairy did it" is just as good as any other for the time being.
First, if there is no God, why are you expending so much energy arguing with me? Who in their right mind would fight to prove the tooth fairy does not exist?
