Whatever God is, the fact that the universe exists proves that God exists.
If only that was so - we wouldn't have 400+ pages in this thread.
We have no evidence of anything that can make the complexity and size of the universe. Whatever could do the making, would fit the general description and definition of God. If it didn't, it wouldn't be able to make something like the universe with all its "furnishings."

''We have no evidence of anything that can make the complexity and size of the universe.'' You are right badecker we don't, why do you claim you do then?
