I was pulling shit out of my ass. Because, from a scientific standpoint, that's the same thing theists are doing when they use this proof. You have the logical conclusion that something transcendent must have acted on the universe to get it started, but you don't include the obvious fact that it could just as easily be an arbitrary, unthinking physical force as an intelligent creator. You may have a very general definition of God, as far as your proof goes, but if you weren't thinking of a specific god, you wouldn't have bothered to try and prove his existence in the first place - I mean, you say yourself, you're trying to prove God's existence. Not "a god," but God with a capital G. And the fact remains that no matter how sound the proof may be, the only way to correlate it with a specific entity or force is with a leap of faith.
