The best argument for the existence of a creator of the Universe if not 'God' is that the universe is so finely tuned to exist that it would take a random infinite number of universes to ensure this universe's existence.
You can argue that either there is one creator or that there is infinite number of universes.

What is most interesting to me is when the idea of the simulated universe (aka the matrix) was put out, many scientists said 'this would answer so many questions!'
So, scientists are willing to say the universe is simulated because they won't say 'God.'
