From my perspective, unless there is something akin to a soul or disembodied consciousness, there’s simply no fact of the matter here beyond the more granular facts. I don’t think “the same consciousness” means anything more than the prosaic ways in which we might define it, e.g. with reference to overlapping chains of experience and memory. We instinctively care about it, but I think that’s fairly easy to explain as a byproduct of our self/other distinction and self-preservation instinct and so on.
