What proof is there of the multiverse? (sh.itjust.works)

I guess I've always been confused by the Many Worlds Interpretation of Quantum Physics and the fact that it's taken seriously. Like is there any proof at all that universes outside of our own exist?

I admit that I might be dumb, but, how does one look at atoms and say "My God! There must be many worlds than just our one?"

I just never understood how Many Worlds Interpretation was valid, with my, admittedly limited understanding, it just seemed to be a wild guess no more strange than a lot things we consider too outlandish to humor.

I hadn't heard about a recent double slit experiment, I'd love to know more. If you have a link, or some info about where it was done, I'd be grateful.

And what's the autonomous body reaction stuff? I'm curious about that too (which I'd always assumed anyway, but if there's research I'd like to read about it).

Thanks!

I got curious too and, since we do have the Internet at our fingertips, here: https://physics.mit.edu/news/famous-double-slit-experiment-holds-up-when-stripped-to-its-quantum-essentials/
