      Scientifically: we don’t know and probably never will, because we can never see outside the universe

      I think: Yes. Look up the “anthropic principle”. We can only explain the many coincidences that caused humanity to be able to exist (stuff like ‘gravity exists’) by the fact that we wouldn’t be able to see them if they weren’t there!

      I like to think that a universe exists for every possible set of laws of physics allowed by maths. That would be nice and neat! However, that has absolutely no evidence whatsoever and you should not under any circumstances (except if we actually prove it) take that as anything more than the daydream of a random person on the internet.
