South African musician and author, Michael Tellinger is the author of the 2005 book, 'Slave Species of God,' as a result of his 25-year study of the works of the controversial yet successful author, Zecharia Sitchin.

The latter was best known for his theories of human origins involving ancient astronauts, known as the Anunnakis, who'd originally settled in Mesopotamia, in search of gold but who it is suggested, through Sitchin's translations of ancient Sumerian cuneiform texts, moved on to Southern Africa where gold was to be found in greater concentrations.

Tellinger believes that he has found the locations of six ancient metropolises in southeastern Africa, each measuring over 60km in diameter, which surrounded major gold mining operations beginning up to 500,000 years ago - and where homo sapiens was ultimately created as a hybrid slave race by the Anunnaki to do the dirty work of their gods in the mines.

Tellinger makes very compelling arguments for this in his interview with Coast to Coast's George Noory.
