The ancient Egyptians began burying their dead in shallow graves but later elaborated on burial practices when they discovered the sand naturally preserved bodies. They began intentionally mummifying the dead to ensure their spirit could live on after death. The elaborate mummification process involved removing organs and drying the body with salt before wrapping it in linen. The dead were also buried with supplies and offerings to aid their afterlife. Eventually, tomb robbing became common and treasures were stolen, leading to harsh punishments for thieves. Finally, mummification practices declined and some began creating "instant mummies" for remedies, until this practice was also abandoned.
