I was facinated with this at first and did a good bit of research myself.
The glaring facts are that most Dogons aren't even aware of the star at this point though some do have knowledge of it. The dogon tribe has no record
of how old the story is and the knowledge might have come after the dicovery of the star.
If you ask a Dogon Tribesman about sirius B it is likely he will have no idea what you are talking about. If he does know, he will tell you it is a
star you can no t see with your eye. Thats about it, no myth of gods, no ancient tale, nada.
The knowledge of Sirius B in the Dogon tribe can only be traced back to the late 1970s. No one in the tribe claims the knowledge is old let along
ancient.
It seems that the story of the Dogon tribe has been blown so out of proportion and told so much via the internet that now it includes dates stated as
fact, ancient tales, and even stories of sky travelers. The truth is that Dogon tirbesmen are likely to not even know what you are talking about if
you ask them.
That being said I didn't write anything about this or keep a list of sources...so when you do research the events keep a few handy.
