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.
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.
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.
