The only real prrof of alien visit on earth:Dogon,nommos,amphibian gods from sirius

The Dogon people are a reclusive tribe of cave and hillside-dwelling farming people inhabiting a sparse, rocky plateau in southeastern Mali, West Africa. They live in the Homburi Mountains near Timbuktu. Isolated topographically and culturally from the outside world for countless centuries, they may well appear on first sight to be exceedingly unlikely receptacles of highly advanced astronomical knowledge ­ which only goes to show just how easily we can be deceived by outward appearances.

They are believed to be of Egyptian descent. After living in Libya for a time, they settled in Mali, West Africa, bringing with them astronomy legends dating from before 3200 BCE.

At the center of their religious teachings is knowledge about a star that is invisible to the eye and so difficult to observe (even through a telescope) that no photographs were taken of it until 1970. The Dogon say they received their knowledge by visitors to the earth from another star system.

The star they describe is Sirius B. Its existence was first suspected by Western astronomers in 1844, when irregularities were detected in the movement of Sirius. It was supposed that Sirius must be affected by a second star, and in 1862 a faint companion star was finally detected. Sirius B is a white dwarf that, although small and faint, is extremely dense and heavy enough to exert an influence on Sirius A.

The Dogon name for Sirius B (Po Tolo) consists of the word for star (tolo) and "po," the name of the smallest seed known to them. By this name they describe the star's smallness...it is, they say, "the smallest thing there is." They also claim that it is "the heaviest star," and white. The Dogon thus attribute to Sirius B its three principle properties as a white dwarf: small, heavy, white.

Dogon mythology says that Nommo was the first living creature created by the sky god Amma. Shortly after his creation, Nommo underwent a transformation and multiplied into four pairs of twins. One of the twins rebelled against the universal order created by Amma. To restore order to his creation, Amma sacrificed another of the Nommo progeny, whose body was dismembered and scattered throughout the universe.[1] This dispersal of body parts is seen by the Dogon as the source for the proliferation of Binu shrines throughout the Dogons’ traditional territory; wherever a body part fell, a shrine was erected.
In the latter part of the 1940s, French anthropologists Marcel Griaule and Germaine Dieterlen (who had been working with the Dogon since 1931) were the recipients of additional, secret mythologies, concerning the Nommo. The Dogon reportedly related to Griaule and Dieterlen a belief that the Nommos were inhabitants of a world circling the star Sirius (see the main article on the Dogon for a discussion of their astronomical knowledge). The Nommos descended from the sky in a vessel accompanied by fire and thunder. After arriving, the Nommos created a reservoir of water and subsequently dove into the water. The Dogon legends state that the Nommos required a watery environment in which to live. According to the myth related to Griaule and Dieterlen: "The Nommo divided his body among men to feed them; that is why it is also said that as the universe "had drunk of his body," the Nommo also made men drink. He gave all his life principles to human beings." The Nommo are also thought to be the origin of the first Hogon.[2][3]
