"If there was nothing before [Yeah, who or what?] created the universe"
That there "was nothing" "before" the Big Bang is just ONE assumption, based on the very likely incorrect assumption there was only ONE Big Bang and before the BB was "nothing".
However, this idea is already very outdated. (Just by coincidence I am reading some book currently where exactly this, ie. new and current cosmological models etc. are talked about).
What we can rather safely assume is indeed that there WAS a Big Bang, from the fact that space itself expands and that we can measure background radiation. There is nothing which would speak against a BB and scientific models and observations confirm it.
However, where it gets interesting is many theories/models what actually caused the BB. Check into "quantum fluctuations of the vacuum", inflation...and new theories like the M theory. Means multiple universes that may exist in "different dimensions", universes where each Universe exists on a so-called branes. Such universes could at some point collide and where they do they can create a Big Bang, ie. it is conceivable and actually seriuosly debated that one universe can be "created" out from on another.
It is also conceivable that there are infinite universes "in different dimensions" alongside ours, infinite universes which like ours are constantly born, evolving, dying etc. Universes may exist with entirely different physical laws as compared to ours, universes where matter never developed etc..etc.
This is not silly "new age" talk, those are some of the latest cosmological models.
Interestingly, from the book I am reading right now, John Gribbin actually states an astonishing thing, although extremely speculative. (Which is rare for him, his books are usually keeping it scientific). He says it may be possible/likely that we, in hundred years, may be technologically capable to create an universe. Pretty mind blowing. He also speculates then in the same paragraph it may well be that this (our) universe was created "as an experiment" by some intelligence in another universe. Of course this is extremely speculative but it is "thinkable", should we at some point be able "to create an universe". If this would be possible, of course "someone" could indeed have "made" the universe, or any universe for that matter.
** Also, let me recap, or at least try...
Quantum fluctuation and then an universe created "out of nothing" would mean exactly that: That it's in theory possible that a universe is created "out of nothing", out of pure "randomness", no intention or aim, whatever, simply because of a quantum fluctuation. In other words: It would be "normal" that universes "just like that" on occasion (or possibly: all the time) pop into existence, and it would not need a guy with a long beard to do so.
