Just jumping into the last page of discussion I don't think there is a parallel universe, alternate ones I kinda assumed were always there. But the more I think about the scared timeline and how they pruned it so there where no branch offs I'm almost willing to say that yeah there aren't or weren't until endgame and They did all the time travel creating new alternate time lines.
In a nut shell, I think now alternate universes can just grow out of control and there is going to be maybe a cross multiversal war that not only involves kang but the introduction of tons of marvel characters.
