(For brevity I'm referring to God as a male.)
I find it somewhat ironic that today physicists and their ilk are expounding on theories that our universe came from nothing. Personally I think its great. However if I believed my universe was created out of nothing by a god then I'm also all over this as a good thing. The problem is that something from nothing is contradicted when a creator is present. Yet if our universe is essentially nothing and we manage to create a god from it then will we actually have taken the first step in theism.....creating God from nothing? IOW's God isn't here yet, we're still working on it.
The first question someone will ask is 'what is your definition of God? Let's keep it simple and say God is a living entity capable of creating universes, life, laws of physics, and at his whim manipulates or changes any law at any time. He also possesses all the knowledge that there is and works in mysterious ways. Not absolutely sure on whether a definition is important so I guess the easiest way to say it is to ask if the universe is capable of manufacturing the god you believe in?
Right off the bat, is it possible for a god to possess everything there is to know about our universe? Does that knowledge have to be solely in the mind of the god or just at his disposal? You'd be correct if this sounds somewhat like Asimov's The Last Question and Multivac. I realize that a giant computer could be the last remnant of intelligence our universe has to offer but something like that would certainly rule out the living entity, would it not?
