Dogon People are of ancient Egyptian descent. Currently, they are indigenous to central plateau region of Mali. Dogon society is organized by a patrilineal kinship system. Each Dogon village is headed by a chief head who is the oldest living son of the ancestor of the local branch of the family. Their astronomical lore goes back thousands of years to 3200 BC. According to oral tradition, a race people from the Sirius System called the Nommos visited Earth thousands of years ago. The Nommos were amphibious beings that resembled mermen and mermaids. The Nommos, according to the Dogon legend, lived on a planet that orbits another star in the Sirius system. It was the Nommos that gave the Dogon the knowledge about Sirius B. The legend goes on to say that the Nommos also furnished the Dogon's with some interesting information about our own solar system; that the planet Jupiter, has four major moons, that Saturn has rings and that the planets orbit the sun. These were all facts discovered after Galileo invented the telescope. The possibility of Sirius B's existence was suspected in 1844 by the astronomer Friedrich Wilhelm Bessel. He had observed that the bright star was pursuing a slightly wavy course among its neighbors in the sky and concluded that it had a companion star, with which it revolved in a period of about 50 years. The companion was first seen in 1862 by the astronomer and telescope maker Alvan Clark. There is in existence of an artefact that is 400-years old depicting the Sirius configuration and as well ceremonies held by the Dogon since the 13th century celebrations of the cycle of Sirius A and B. The Dogon’s knew about the super-density of Sirius B, a fact discovered not so long ago. The Dogon have their own system of astronomy and calendrical measurements, anatomical and physiological knowledge, as well as a systematic pharmacopoeia. Preserved a tradition of contact with intelligent extraterrestrial beings from the Sirius star system. These beings taught the arts of civilization to their ancestors.
