There are a number of such stories which tell about landforms which have been under the ocean for 11,000 years, since the great meltwater pulses raised the ocean at the end of the ice age. Long after the stories were documented by anthropologists -- who thought it was unusual that so much mythology would be concerned with the topography of the seafloor -- sonar was invented, which confirmed that the landforms existed more or less exactly as the stories said.
So personally I think that's pretty hard proof of at least 11,000 years of accurate oral tradition.
“Prophecies” is a very euro-centric way to dismiss the subject. Indeed, there is encoding for you to be discovered, which has been rigorously demonstrated.
Dig deeper.
Why is the dismissive non-curious comment not getting down voted?
Am I in denial about whether the curios community still exists here?
To recognize the topic on hand... When a native community shares an oral tradition that accurately describes something that's been under water for 12+ thousand years despite not having the technology to map the sea floor that's pretty strong evidence in the accuracy of their ability to persist accuracy through oral tradition.
Parent is entirely valid in encouraging curiosity in this subject to anyone who is dismissive of it.
TLDR: the story is about a constellation that is seven sisters, but one is hiding; and that constellation does indeed have seven stars, but one hasn't been visible for 100k years.
