But then you are describing only part of the system using QM. The whole
system includes the universe itself, this is described by a
wavefunctional that assigns amplitudes to entire space-time
configurations and the fields in it.

It's a unitary map, it will evolve the past state into a superposition
of many different states. One may argue that this is meaningless, as
one has to choose a basis. But this is essentially what time evolution
operator does for you. If you work in a particular basis then applying
the time evolution operator amounts to changing that basis into
another basis without affecting the state of the system in any way.

Why do you think the evolution is deterministic of our part of

The time evolution operator maps past states of our universe to
present states. So, the present state of the universe, which
includes our conscious experience of the present state was also
present in the early universe in a nonlocal way where there would be
no obvious sign of us existing at all.

I think the idea is a bit silly because I don't see any way to
prove
or disprove it even in theory. And in the entire universe the only
thing that I know with absolute certainty is sentient is the 3
pounds of gray goo inside a bone vat that is sitting on my
shoulders.
