Interesting! I once read that these tribes are related to Bushman and Pygmy tribes. I know throughout Southeast and South Asia there are Black tribes, including Negritos.

I would not be surprised if they have legends of strangers from a civilization that existed 10,000 years ago. I suspect they would be Ainus/Vedda/Polynesians.

Nah. They are about as closely related to you as they are to the Khoisan Bushmen of Africa.

The human branch that produced everyone on earth today no longer exists in Africa, it went extinct there long ago.
