The supposed literalists do, as represented everywhere. I wasn't referring to you or anyone here.

Sorry, I misunderstood you.

Have just found something very interesting related to snakes. World's Oldest Ritual -- Worshipped The Python 70,000 Years Ago

The python is one of the San's most important animals. According to their creation myth, mankind descended from the python and the ancient, arid streambeds around the hills are said to have been created by the python as it circled the hills in its ceaseless search for water.

I'm not sure about this suggestion, though.

The shaman, who is still a very important person in San culture, could have kept himself hidden in that secret chamber. He would have had a good view of the inside of the cave while remaining hidden himself. When he spoke from his hiding place, it could have seemed as if the voice came from the snake itself. The shaman would have been able to control everything. It was perfect." The shaman could also have "disappeared" from the chamber by crawling out onto the hillside through a small shaft.

It seems that Shamanism in San culture isn't a one person occupation.
