I'm not sure that argument is entirely fair to the Deists. Assuming you have an entity who can create universes, influencing things that happen 14 or 15 billion years down the line during creation doesn't seem much more incredible than the premise.So when the deist argument is phrased as "Suppose God created the universe then had nothing more to do with it", I'm forced to ask "Suppose what created the universe then had nothing more to do with it?"
Of course this argument quickly becomes moot (predestination versus free will) so screw it, it doesn't matter.
I was wondering if we can come up with a hypothetical description of God. I mean if we can't, then there's a semantical problem with the concept, and we can't even discuss it. I'll put forward: "Can accomplish anything within the universe, and knows everything that occurs within its bounds (all-powerful and all-knowing)"
