George Noory interviews Robert Temple about his book The Sirius Mystery and the Dogon tribe of Mali.
According to anthropological studies, the Dogon Tribe of Africa developed a religion based on the Sirius star system and were aware of Sirius B (a companion star that can’t be seen with the naked eye) as well as a third star in that system which wasn’t confirmed by astronomers until 1995, nearly 20 years after Temple wrote about it in his book.
The Dogons believed that beings from a planet in the Sirius system came to Earth in the distant past, landing in a place where their ancestors came from (Temple suggested that this was probably Egypt). These ETs were slimy, air-breathing aquatic creatures that had fish-like tails and arms without elbows, and he noted that similar beings have also been described in ancient China, Greece, and Sumeria. The Dogons said that when the ETs were here, a new star appeared in the sky that disappeared after they left. Temple surmised that this was likely their orbiting mother ship.
