I'd like to think that when we die, we reincarnate. Not necessarily another human being, though. Buckle the fuck up, the below read is quite a journey through the local cosmos.
We're all made up of a bunch of atoms. Biomass, I guess. Somehow, you are these atoms that make up your body, compared to other fully-assembled organisms around you.
I'd like to think we are a singular atom, sitting somewhere in the brain. Or perhaps we're a group of atoms led to believe we are "one". Regardless, you are here, sitting there in front of your screen, probably touching yourself at this very moment.
If you were to die, the established atomic/molecular/biological system that makes you "alive"... shuts off. You are now just a pile of "non-living" atoms, destined to decay, which is really just your masses of atoms being recycled elsewhere: bug shit, fungi food, soil nutrients, people food, etc.
When you die... you, the atomic "soul"... you just get pushed around elsewhere in this earth. Your old body rots behind, you get eaten by a maggot that found its way into your old brain, you then become a protein to create a nutrient to an adult fly, the fly gets eaten by a frog, the frog metabolizes the fly into frog parts to build its muscles, the frog gets captured and eaten by a drunk Korean guy, the protein from the frog gets transferred to the Korean guy's balls, you then become a sperm in the testicles, then the Korean guy hits it up with a whore in the red light district of Seoul, and boom! You are now a miserable Korean baby! Shit like that.
Hopefully, you don't get aborted, let alone get beaten to the egg by the millions of other sperms (they will end up in the toilet or just dry up as leg-dribble). There's also variables such as... well, being here on Earth, the only planet for trillions of miles around that's able to support an environment for molecules to wiggle together, coalesce, and become fucking LIFE. Here's to hoping this planet won't explode soon!
It could be a year, a decade, a century, a millennium, or even longer before you become another sentient being. It's the beautiful circle of life. You won't remember anything about your past "life"; all of your memories died with the old body. You just exist; you're a traveling little figurative "soul" going for a fun ride in the universe, vessel to vessel. You probably have eons of afterlife to spend as a boring blood cell or something. You probably won't be a human next time. Maybe you'll be a plant.
Rest assured, the concept of time and boredom likely resides in our human minds. When we reincarnate into boring shit like cells and plants, it'll all happen in a human blink of an eye! You'll become another sentient thing before you know it!
That's what I like to think when it comes to death.
I also believe we should eat each other if we want to ensure our reincarnate fates as another human. Just a very good suggestion.
