Résumé
When and where was the Rigveda (Rv) composed? How are the Vedic people related to the vast Harappan archaeologicaltradition? These quintessential questions have no direct answers. At our current level of understanding, archaeology andsacred texts constitute two distinct streams which do not intersect. We must therefore collate evidence from differentsources and try to produce a synthesis. It is particularly important to take note of archaeological evidence from Central Asia,because it has not received the attention it deserves. What is well known in science must be kept in mind in the case ofhistory also. A theory to be valid must explain each and every fact (known at present or to be known in future) in a selfconsistent manner. Conversely, even if there is one piece of evidence that a theory is unable to explain, it should be put onhold, modified or even rejected.
