Math is what man created to explain Nature. Math is an abstract not a concrete and as such merely describes natural processes. It is not a proof of God rather a proof that man can create system by which he explains his universe.

Well, that's neat and profound and all, but tell me, when mathematical instruction sets are physically processed in the real world, is that abstract or concrete?
