I think this goes in this board, but here goes
I remember reading about this in my favorite book, Mysteries of the Unexplained...
Tribesmen in African were given knowledge of a star that they said they came from, to a group of African Tribesmen. The trouble is, this star was
completely invisible due to the brighter stars in its proximity until recent science revealed it.
The aliens they got it from were supposedly amphibious, having had to land in water first and then climb out to meet with the curious(and frightened)
tribesmen. They then left after giving them the knowledge of the star they came from, I forget what it was called, in addition to other knowledge.
I forget the rest, if anyone could flesh this out for me it would be great, I think the star is by Sirius, I don't know. I tried to research it but
only got hits on satellite radio
I don't think this was posted before, plz help!
