Alternate universes were created for people who make bad predictions.

They can just claim we moved “into a new timeline”.

And for people who want to deny the laws of probability. You can just claim there are infinite multiverses so no matter how unlikely your story, it was bound to happen somewhere.

By definition if we can sense it, it's not another universe it is just part of our own. And if they can't sense it, there's no basis for imagining it is real. So the multiverse concept is just blind faith in the employ of wishful thinking.
