So then who created the creator? For if he always existed couldnt the same be said for the universe?
This post is rather abstract, but I think there's an important difference between an uncaused God and an uncaused universe/multiverse: they would be infinite in a different way.
If the multiverse has always existed then the multiverse has existed for an infinite length of time - unless it's timeless. It's probably not timeless, because then why would an inanimate timeless object be 'set up' to create a temporal universe (a radically different type of thing)? That wouldn't make sense.
This makes the multiverse an infinite by successive addition. So then the multiverse is like someone who started doing 1 + 1 + 1 +1 and so on forever an infinite time ago, and has now reached infinity. This is a bit of a counter-intuitive idea; it may make sense, but it is different from what applies to God (see below).
God would be an infinite by nature rather than successive addition. What this means is that unlike the multiverse, God wouldn't be an infinite composed of infinitely many parts. God would, instead, encompass a kind of reality that encompasses everything in a way that doesn't contain within itself parts/distinctions/discrete objects. This would, by definition, be infinite. But
not like the multiverse infinite of successive addition.
So, assuming that this distinction between an uncaused God and an uncaused multiverse makes sense, you do have a basis for saying that they could be quite different.
I personally don't think that the multiverse infinite (by successive addition) makes sense, essentially because you just can't count up to infinity, it seems to me. A qualitative infinite makes more sense. So maybe you can rule out an infinite multiverse for that reason.
