For a local observer spacelike separated events do no exist until they come into causal contact with it.

That sounds like mind projection fallacy. That the observer does not know about the events doesn't mean they don't exist.

That's the earliest time that can be called a measurement time.

That would imply that whatever measurements we make locally, from the perspective of an observer who hasn't yet interacted with those measurements, our wave function hasn't collapsed yet, and we remain in superposition.

So, how does it make sense that the wave function has collapsed from our perspective?

"Exist" should be a taboo word, until you can explain it in terms of other QM concepts.

For a thing to exist, it means that thing is part of the reality that embeds our minds and our experience, whether or not that thing has an effect on our minds and our experience. Of course when I say something exists, it is a prediction of my model of reality. And you might ask how I can defend my model in favor of an alternative that says different things about events with no effect on my experience, and my answer would be that I prefer models that use the same rules whether or not I am looking, in which my reducible mind is not treated as ontologically fundamental.

"Reality" is another taboo word. We have no direct QM experience.

I prefer models that use the same rules whether or not I am looking, in which my reducible mind is not treated as ontologically fundamental.

If there is a single lesson from QM, it is that looking (=measurement) affects what happens. This has nothing to do with minds.
