Please list these books and sources. An 8000 year old timeline is quite a leap over the current consensus which is 3500 years (the Rigveda, whose earliest inscriptions are found way outside the subcontinent all the way over in Syria).

Also what is the Saraswat Valley Civilisation? Are you referring to the Indus Valley Civilisation?

I’m sorry but the Out of India hypothesis is not accepted in the scientific and linguistic consensus in any way. The migration is believed to be in the other direction.

Also, Panini himself distinguished between different forms of Sanskrit as I understand.
