The correct answer to this open question is the following.
Cultures and Societies of the Indus Tradition,
These communities can be linked to VEDAS, however, they were not Vedas, these ancient Indus Valley people preceded teh Vedas, which means they lived before.
We are talking about one of the ancient civilizations on planet Eart: the Indus Valley Civilization also known as the Harappans.
These Harappans settled next to the banks of the Indus River, in Asia. They are considered to be one of the oldest civilizations as well as the Sumerians in Mesopotamia and teh Ancient Egyptians in North Africa.
Historians consider that the Vedic ástolists came years later from teh Aryan people that came from the Middle East.
This Indus Valley people or Harappans did not leave any record of their history, that is why archeologists or anthropologists do not know anything about them.
