From where I'm sitting, it looks like death should not be the end in that case.
You can't perceive the passage of time when you are dead, so you're just going to experience dying and then immediate rebirth after the countless eons pass for that rare moment where entropy spontaneously reverses to form your mind again.
With scientific premises isn’t it more likely an identical “you” lives the exact same life that you did independently, rather than your consciousness picking up where you left off? Maybe Nietzsche was right, lol.
I didn't really get to the topic of consciousness. IMO if poincare recurrence happened, there's no reason to think that the new 'you' would continue your consciousness, it would just be a different person who lives the same life. But we don't know how consciousness works.
