Why do we immaculately preserve our dead bodies? Then bury them 6 ft underground. When in a billion years, aliens find our cold dead rock embedded with all of these perfectly preserved human bodies in ornate caskets, they're going to wonder why we're such weirdos with our dead. They're going to wonder if we sometimes dug them up to admire them, otherwise why go through all of the trouble. We don't, but they'll think we did! My family knows my wishes to just be tossed into a hole or cremated, and don't spend more than $100 on it. So probably just the hole, that's fine. I won't care either way, thank you. They'll of course NOT abide by that wish, and do the weird preservation shit with my dead body.
