I have written a hub about it.
I can't really prove if God exists, although I believe that there must be a God.
I think even the traditional atheistic darwinian evolution, which I believe is mostly a hoax, proves that God exists. Think of it like this:
Darwin says that everything evolves into something more complex. This reflects to the existence of God in two ways:
1. humans are part of nature of Earth. Earth is part of the Solar system. Our solar system is part of the Orion arm of the Milky Ways galaxy, which is part of the whole galaxy, which is part of our cluster and supercluster of galaxies, Then, our supercluster of galaxies are part of the universe, Our universe is part of the multiverse, which could be part of God.
2. If God was before creation, then during creation, God EVOLVED into energy, that to atoms, atoms to molecules, molecules to cells, cells to microscoping animals, those to small animals, those to humans, and probably we humans are also evolving into something else according to Darwin.
