Wait a minute - I am the godless somethingorother...
Weather or not god is a physical being, I don't see how you can think that it simplifies a complex process to say "god did it". Adding a god to a process makes it more complex, even if you think it is a sin to look under the hood and see what makes that god tick.
Regardless of what the god is made from, astral ether or whatever, the result is the same - you have to be orders of magnitude more complex than the world that you manipulate.
Well, I think that math is awfully complex. Therefore, it must have been created by a more powerful being than Iperhaps Isaac Newton or my math professor Bob.
The logic is wonky. But whatever.
Faith requires doubt. Faith requires the possibility that this thing might not be so. To render God empirical is to remove this component, and as a result, I would argue, destroys religion.
