Honestly I find multiverse theory somewhat stupid. There is zero proof of it at all. It's a thought experiment. It makes as much sense to me as believing in God. It's humans attempting to answer the same questions our ancestors asked which led them to invent religion. It adds little value except to make us sleep better at night. In fact, no. Scratch that. Believing in God makes more sense to me than believing in a multiverse because at least a belief in God actually has impacts on one's life. The multiverse is vain imaginings. And it still doesn't answer the question of why there is something forking its way through whatever it's in in the first place. It doesn't answer the question of why the world exists. It just says there are lots of them.
