Proof that God doesn't exist

[Undeceived]

The way i understand it, negative energy is the conclusion an argument using the Big Bang as one of its premises. NASA: "It is unknown in physics whether negative mass or negative energy densities can exist." http://www.nasa.gov/centers/glenn/techno...paper.html
Basically, it is a theory on the level of wormholes. If you could prove that negative energy actually exists (as opposed to a mere lack of energy), you'd be proving the potential for time travel. Not to say that's not possible, but do you have any evidence for it?

Evidence for negative energy densities? That's actually the first time I've ever heard of that. I'm pretty sure the 1st law of thermodynamics states that in a closed system, i.e. the universe, the total energy is equal to zero.

The energy would have to be constant if our system is an isolated system. (http://en.wikipedia.org/wiki/First_law_o...modynamics ) The universe of the theoretical Big Bang has to be an isolated, closed system. The story of Creation says that the universe was not always closed--an outside source served as catalyst for all its energies, namely God. You need evidence that our system has always been closed, but that knowledge is unreachable. So I still don't know why God would use the Big Bang because there seems to be nothing more known about the Big Bang than about Creation. In the beginning there was a burst of energy from one place--what else do we know? Do you have any other arguments why a creator would use the Big Bang?
