A Northwest African Tribe known as the Dogon have knowledge of a distant invisible star in the Sirius constellation call Sirius B. They have had this knowledge for at least 1000 years and received it without the use of any telescopes. This same knowledge was also known to the Ancient Egyptians - because of this - along with their migration into their present territory (from Egypt into Mali), it is not hard to believe their Ancestors are the Ancient Egyptians.
