Ashi...you got me thinking about something. Did you know that if you were to immerse yourself in a tank of warm water that is the same temperature as your skin, and shut out all sounds and light, that in a few minutes you would be having full blown hullicinations? That of course is what we call sensory deprivation.
Now consider how much more difficult it would be for a lifeform that is supposedly the most complex and advanced thinking, feeling, caring, loving, divinity around...to be locked in the same condition...with absolute nothingness for uncountless trillions upon trillions of years! I really think this is a more difficult question to answer than where God came from.
There would be no interaction with anything. Nothing to show love for or care about. To survive in this state, a lifeform COULDN'T have any feelings. What would any of us do if we were sentenced our entire lifetime in solitary confinement without a single sound, sight, feeling, or interaction with another being. We would be dead that is what, or completely stark raving mad.
If you are completely self contained...nothing can happen. You can have no ART, for this requires the interaction of others, you can have no music (at least as we know it), no dialog, zippo. Maybe you could play with mathematics for a few million years and come up with what digit of pi you end up with after all that time...woohie sounds like fun to me! Thus, I think it impossible for such an existence to last in uncountless time. I also think our universe may have evolved some very incredibly advanced lifeforms (probably machines) that we could consider God-like because of their development to our own, but they didn't create the universe or us.
But regardless, the idea of what is God-damned to me, would be the idea of spending eternity all dressed up and nowhere to go.
