the Dogon people of the nation of Mali in Africa have a creation story that follows as such. meramid-like E.Ts came from the sirius star system and inter-breeded with human beings bringing about the dawn of civilization. another thing they brought was cannabis. these people have a yearlong celebration that lasts a year and makes the cannabis cup look lame. the festival coincides with the completion of the orbit of sirius B around sirius A. this was something that the dogon people had in their own lore for thousands of years but was not confirmed by astronomers until 1970. they also knew of a sirius C, which was "discovered" by french astronomers in 1995. i tend to believe the rest of their story about weed coming from the sirius system, since everything they claimed about it that can be proved is true. look it up on the net.
