Archaeologically, during the aforesaid period and within the above-noted territory, there existed one and only one civilization, namely the Harappan. Hence, the Harappan Civilization and the Vedas are but two faces of the same coin (pp. 122-23). Further, the evidence from Kunal and Bhirrana (pp. 54-55) establishes that the roots of this civilization go back to the 6th-5th millennia BCE, indicating thereby that the Harappans were the sons of the soil and not aliens. Thus, the Vedic people, who were themselves the Harappans, were Indigenous and neither Invaders nor Immigrants .
