Actually it is what information theory is about.Information theory however has advanced to include physical, and digitized information. And you will find that many fields consider energy =/= information. In fact if you have read my article on information theory you would have realized that this is true. And I did give the definition of that particular god. And when I give an abstract, it's a quote from the source material.. I'm telling you this because I was christian and that is the definition used.. Especially in Orthodox Christianity.
Yes it remains ambiguous to a point, but that's essentially the definition of god. At least the most complete definition you will get in regards to the Christian GOD.
If you were looking for a definition that could be applied to all GODs, you won't find one.
100% positive there is no God?
Well, no - but, I'm not 100% positive about anything.
I'm fairly certain that all the "deity" and "creation" myths are just really myths - as most of them are simply absurd and have no supporting evidence.
As to "proof" - ultimately, one can only "prove" mathematics and gain evidence for the existence of something. You can't "prove" something doesn't exist, you can only gain evidence for it's contrary.
