History should be based on evidence or belief?

The new Chairman of ICHR has a deep faith in Ramayana and Mahabharata and that's great. But where I disagree with him is :
"The writing of history cannot depend only on archaeological evidence. We have to depend on folklore too."

History should be based on evidence not on hearsay.

 I am sure, many from my generation sat in front of TV every sunday to see Mahabharata and Shree Krishna on Doordarshan.If he feels strongly about learning from Mahabharata and Ramayana, Introduce it as optional learning. There was Catechism subject at St. Paul's H.S. School alternatively with moral science.

But I am not for modifying text on the basis of folklore. Next Harry Potter may become the new God!
