the Jews were a people group, there is no such as 'Indian', there is nothing to resurrect since it never existed in the first place.

'Indian' is the same as 'Bharatiya'[1], which is as old as human civilization gets.

And I agree with OP that Sanskrit should be revived in India like the Jews did for Hebrew in Israel.
