Is Quantum Mechanics saying we've already existed and will again?

[Seminole Boy]

This is what I'm gathering about quantum mechanics. There is absolutely no free will. Every single form of motion in the universe is already predetermined and has already happened in another universe. And it will happen again.

Everything is a rapid replication of everything and will just keep happening (universes replicating).

There is absolutely no free will.

That question is independent of quantum mechanics, and purely depends on your definition of free will.

Every single form of motion in the universe is already predetermined

That depends on your favorite interpretation of quantum mechanics.

and has already happened in another universe.

There are no indications of any other universes. Your last line seems to be refer to the many-world-interpretation of quantum mechanics: There, everything possible does happen in some "worlds" (or "branches").
