Assume it is impossible to prove God does not exist. Then the probability that God exists, , however minuscule, is greater than zero: . Also assume, as many important physicists and cosmologists do, that (1) the multiverse exists and is composed of an infinite number of independent universes and (2) our current universe is but one of those infinite universes existing in the multiverse.*

If the probability of the non-existence of God, denoted , in some universe is defined as

then as the number of universes (*n*) approaches infinity,

.

That is, the sequence as . Any event that *can *happen will ineluctably happen given enough trials. This means God must exist in at least one universe within the multiverse, and if He does, then He must exist in all universes, including our universe, because omnipresence is a necessary condition for God to exist.

Q.E.D.

* This is certainly a reasonable, if not ubiquitously held, concept that follows from the mathematics of inflationary theory. In *Our Mathematical Universe*, for example, Max Tegmark suggests if “inflation…made our space infinite[, t]hen there are infinitely many Level I parallel universes” (121).
