Math is a human invention. That some of nature expresses this mathematical compunction is a human expression, a need to find pattern, and therefore, according to this kind of thinking, a divine impetus. Nothing wrong with that, except that it doesn't prove a divine origin, only the desire for a divine origin. When we measure anything that doesn't fit the measurement we call it untrue, or unimportant, or nonexsistent, or we ignore it. But as Neil Bohrs points out--when we measure light as a particle it becomes a particle, when we measure light as a wave it becomes a wave. Well, when we measure the universe as mathematical it becomes mathematical--a self-fulfilling prophecy.
That we don't have answers to questions, that's not a proof that god exists. That math proves things we can't comprehend, well, that's a kind of comprehension in itself, therefore the statement is contradictory and defies truth. No, humans are just incapable of certain things, just because we are doesn't mean there has to be god. This idea that the universe has to make sense is so prejudiced, so math-centric. Math is simply an opinion that we foist upon ourselves because we've got nothing better at our disposal to explain things. Math is our Greek Mythology, our Geek Mythology.
Bottom line: if humans look for something, they'll find it whether it's there or not, hence God and his weapons of mass destruction.
Claiming there's a god is like claiming ghosts exist. If you've seen a ghost then it is material. If it's material then it's of this world, not the divine world. If you've felt a ghost or God, then you're expressing its materiality, and hence not divine. Now if you want to claim that divinity has materiality, then as many people have seen The Loch Ness Monster or Bigfoot as have seen God, or they're some strange equivalents. Come to think of it, if Math measures materiality (even if unseen) and if it is the proof of god, then god is material. So would god just show himself, could he just stand up and be counted. Please. Would you try and stop those who kill in your name. You're getting a bad rep, my friend. Math as a proof of God--that's a good one.
