He is the complete and utter omnieverything deity of the Evenki people of Siberia. He lives in Heaven and rules over all.
The Evenks are traditionally hunter-gatherers and their original religion was based around nature, in a similar way to that of Native American Indians. There are — or were — shamans, animal spirits and a profound respect for the living environment. Some of their original animalistic beliefs go right back to the year dot.
Meanwhile, BUGA remains elusive. Does he still rule over parts of Siberia? So far, none of the researchers we’ve sent there have reported back.
