Here is something from the Scientific American. It’s an article by Laura Kehoe, Mysterious Chimpanzee Behavior May Be Evidence of “Sacred” Rituals:
“Even more intriguing than this, maybe we found the first evidence of chimpanzees creating a kind of shrine that could indicate sacred trees. Indigenous West African people have stone collections at “sacred” trees and such man-made stone collections are commonly observed across the world and look eerily similar to what we have discovered here.”
Apparently, this has never before been observed and documented. It is an amazing discovery. Along with tool use, it points toward a central building block of primate society.
I immediately thought of the first evidence of settled civilization. Before humans built homes for themselves in settlements, they built homes for their gods. These first temples likely began quite simply, maybe even as simple as a pile of rocks.
Human society, as we know it, developed around ritual sites. This may have begun much earlier with the common ancestor of both humans and chimpanzees.
