Dear Manju, Your claim that sanskrit existed 1000's &1000's of years is baseless. Read more linguistics. There is no proof for it. The oldest known Indian literature in records is a grammer book in Tamil titled Tholkappium dated between 500 B.C and 200 B.C. Even it belongs to the second sangam and it points the existance of several literary works belonging to first Sangam & Second Sangam like Agasthiyam. These scriptures existed before Tholkappium were destroyed due to floods & other natural calamities. The same Wikipedia says that 55% of all the stone inscriptions found in India are in Tamil. The first sanskrit inscriptions found in India belong to 160 A.D whereas the Adichanallur inscriptions date back to 600 B.C to 500 B.C. Some of the second Sangam literature takes of Kadalkol(Tsunami) destroying Poompuhar which is not recorded in other literature.
The proto-dravidian language that you are mentioning is nothing but proto Tamil and the difference between these two is very limited as the language has not changed much during the course of time due to its independent evolution. Wiki says the first inscriptions in kannada date to 230 B.C. The earliest kannada is free of Sanskrit as Sanskrit was evolving during this time. Please dont do cut and paste, analyse the facts and post it. There are umpteen number of evidence to prove the antiquity of Tamil. I am ready for a constructive debate on this but not in this forum.
