For me, the amazing thing is the existence of all things. It is, if such a thing exists, the Grand Unified Theory. If such and explanation can be found, then how could one not call it the face of God. The funny thing is that such a theory will most likely be understood by only those capable of the higher math that proves it. It will be no unlike another religion, where the knowledgeable priests pass know the Truth that they know. I'll still call myself an agnostic, because I don't think humans are capable (at least at in this stage of our evolution) of truly seeing the whole face of God. Even if the brightest minds find a Unified Theory, how will we know that this applies to the infinite? In its very nature, the infinite is God, and all we know is the only proof we will ever have of it.
