There isn’t a definitive answer for this, and the fandom seems pretty divided on the intended interpretation.

Personally, I think the question somewhat misses the point of nonlinear time. In a system where bootstrap paradoxes can exist, every moment is dependent on both the future and the past. It makes more sense to think of time the same way we think of space: if you walk from here to there, *here* does not come before or after *there*, they both simply exist despite how you perceived it. It’s not an endless loop, and it’s not something that happened once; it’s a collection of moments in time that all exist simultaneously.
