There is no God
Given: Gods are omnipotent, eternal, and omnipresent
Einstein's Theory of Relativity, E=mc², states that the universe is either contracting infinitely into a black hole or, more likely, expanding infinitely. If the universe is expanding infinitely, as supported by Hubble's observations, the energy that is causeing stars to "glow" and give off light will eventually extinguish as the universe continues to expand. This will result in an infinitely large universe at an equilibrium temperature of absolute zero. If the universe has an end, it also must have had a beginning, commonly thought of a "The Big Bang", suppported by the observation of microwave radiation beyond the edges of the first star. If the universe has both a beginning and an end, it is not eternal and therefore, if a god is eternal, a god does not exist.
