You can't even be sure that quantum mechanics is as it seems. Most of it is theoretical mathematics, and while we are "on a roll" when it comes to using these equations to make technology work we are still a long way from knowing "the ultimate nature of reality". I honestly think the idea that the universe "came from life" is stupid though. The idea that we are somehow dreaming reality itself logically necessitates the baseless existence of fully sentient beings that popped out of nothing in order to form the basis of a reality which only exists because it is somehow perceived before it exists. That idea is just as stupid (and very similar) to a belief in God.
