Proof that God exists

[GrandizerII]

That's assuming the verified one.  Have a look at 50:00 to 55:00 here https://www.youtube.com/watch?v=6k6BuYK_PwQ

There is no verified interpretation of quantum mechanics. There's the conventional interpretation (Copenhagen) and there's the increasingly popular interpretation that more and more relevant experts are adhering to (Many Worlds).

What can be observed should be seen as distinct from the interpretations of what can be observed.

Many worlds is deterministic?  I never gave it much thought because many worlds seems a giant waste of energy.

Have you ever read or listened to Sean Carroll? If not, you should give him a try. He says it's quite the opposite. He argues that MWI is the simplest explanation of the quantum happenings.
