The very fact that things didn't go differently is an interesting bit of subjective evidence against atheism. Not necessarily for the existence of a God, however: randomized evolution and quantum mechanics could be preserved by the parallel universes theory, in which case we're in this universe because we've evolved to be here, and there are plenty of other random universes where things had gone differently, and thus, some different form of us is in our stead.
Given both possibilities though, I think Occam's Razor, though often used to disprove God, argues for God in this case, if for nothing else than one supernatural entity is less than an infinite number of supernatural entities.
Still doesn't mean any one religion is correct though.
