Probability dictates Inevitability. Time makes all things inevitable. As time progresses in our timeline (forget the rest), there is, every waking zeptosecond, there is a theoretical dice rolled for every possible scenario that you could ever think of, no matter how unlikely or unrealistic the scenario is.
God merely existing is one of those scenarios and if at any point in our timeline that dice lands on anything which trips the probability for even a zeptosecond, it would imply that God not only existed in that zeptosecond, but due to his omnipotent and omniscient nature, transcended time and space and exists paradoxically across every waking moment of eternity. The Multiverse and other timelines exponentially increase those odds.
TL;DR repent mother fucker, God, and every other comforting or horrific entity you have ever envisioned exists somewhere.
