If you think about it it is not strange at all, it is maybe one of the very early things that differentiated us from animals. We have a concept of death and time, future and loss. We mourn our dead. And I strongly believe that all the rituals that we have established are not meant for the dead but in fact serve the living. It is a way to cope with the loss of a person. And with the ever same ways - casket, flowers, music, burying - we give the mourning something to do and get distracted so that they don't lose themselves in the sadness. It feels "right" because it feels familiar, everyone does it this way. You don't have to reinvent the wheel every time someone dies. How to cope, and how to get rid of the body? Well, there is a societal playbook for that.

There was a dude here on lemmy who actually specialized in American death rites. I think he stopped using lemmy though because of too much negativity, I think people commenting how stupid it is that we don't just trash our dead on a post was his tipping point. Which is a freaking shame because it sounds like he knew some really fascinating things.
