The Indus-Saraswati Valley Civilizations spread over
more than 250,000 square miles, and included over
1600 sites. Most of the villages and cities were laid out
on an exact north-south grid on sites west of the river,
and were built with kiln-fired brick of uniform size.
Sites have been found dating from 6,500-7,000 BC.
Excerpts from three chapters of a book in progress by Dr. Kenneth Chandler expose many misconceptions about the origins of Vedic civilization that were promoted by European scholars of the 19th century. The first chapter summarizes archeological research to dispel the myth that the Veda was created by outside invaders of India, called the Vedic Aryans, who were supposed to have brought civilization into India from somewhere in Western Asia. He also examines, in the second chapter, new evidence that may push the dates of beginnings of the Vedic tradition back well into the third millennium BC or before. In the third chapter, he looks at the contributions of Vedic civilization to modern science and mathematics and traces the lines of influence from Vedic India to Greece and Europeans civilization. http://sanskrit.safire.com/pdf/ORIGINS.PDF
