The main center of Harappan civilization is the newly rediscovered Sarasvati river of Vedic fame. While the Indus river has about three dozen important Harappan sites, the Sarasvati has over five hundred. The drying up of the Sarasvati brought about the end of the Harappan civilization around 1900 BC. As the Vedas know of this river they cannot be later than the terminal point for the river or different than the Harappan who flourished on its banks.

Harappan culture should be renamed "the Sarasvati culture" and the Vedic culture must have been in India long before 2000 BC. No evidence of any significant invading populations have been found in ancient India, nor have any destroyed cities or massacred peoples been unearthed. The so-called massacre of Mohenjodaro that Wheeler, an early excavator of the site claimed to find, has been found to be only a case of imagination gone wild.  The sites were abandoned along with the ecological changes that resulted in the drying up of the Sarasvati.
