The difficulty for any theory is explaining why anything exists at all, i.e., if there's no space and no time, isn't that a stable state? Without time, how could anything ever happen?

If a multiverse theory could give a way to get a universe out of nothing, it would be a lot more elegant than a deity theory. The deity theory after all is incomplete, it just supposes that our universe is embedded inside some sort of "outer" universe where deities live, but that outer universe also has to be created somehow.
