Why is there no evidence of a multiverse theory?

Hello, Miles Alexis Palmares !
Basically because of the horizon problem: we cannot see anything directly from before 380,000 years after the Bang and infer indirectly back to about a trillion trillion trillionth of a second after the Bang.
As far as multiverse theories go, most of them require us to see before the Bang, and because of the horizon problem, we can’t.
The predictions from the few remaining hypotheses, like the many-worlds interpretation of quantum mechanics, would be indistinguishable from the predictions of their non-multiverse predictions. So any evidence we find would also be evidence of the non-multiverse.
