There is one mystery I will concede that science may not be able to answer, and that is the question of what existed before our universe began. One answer is the multiverse. According to the theory, multiple universes each had their own genesis, and some of these universes gave birth (perhaps through collapsing black holes) to baby universes, one of which was ours. There is no positive evidence for this conjecture, but neither is there positive evidence for the traditional answer to the question—God. And in both cases, we are left with the reductio ad absurdum question of what came before the multiverse or God. If God is defined as that which does not need to be created, then why can’t the universe (or multiverse) be defined as that which does not need to be created?
In both cases, we have only negative evidence along the lines of “I can’t think of any other explanation,” which is no evidence at all. If there is one thing that the history of science has taught us, it is that it is arrogant to think we now know enough to know that we cannot know. So for the time being, it comes down to cognitive or emotional preference: an answer with only negative evidence or no answer at all. God, multiverse or Unknown. Which one you choose depends on your tolerance for ambiguity and how much you want to believe. For me, I remain in sublime awe of the great Unknown.
