Something I take some comfort in is that regardless of what your soul does upon death in the short term (whether it's an afterlife of some sort that we don't understand, a nihilistic void of nothingness, reincarnation as the soul attaches to a newly created body somewhere else in the world... whatever, no one alive truly knows or could ever know), science believes in a sort of reincarnation.

Where eventually as step one, everything that ever was ends up in black holes, and those black holes eventually decay until the universe is nothing but a uniform background of unchanging radiation, referred to as the heat death of the universe (because nothing can really physically change on macroscopic scales anymore, in order to convert energy into new heat).

And then, after ridiculously long time periods, quantum fluctuations cause the machinery of the universe to start back up again, everything re-forms, and eventually our universe ends up back where it started at the beginning of your life.

So it's possible that you will live again, and again, and again, forever, just with no ability to remember how it went down last time. And an incredibly long wait between lifetimes (though, to be fair, if death is a nihilistic void for each person, that wait is only going to feel like two seconds and bam, you're right back in the womb).

So if nothing else, at least there's that.
