Brahui Language Balochisthan Dravidian ,Dravida Invasion of India?

When one studies the Dravidian literature in conjunction with Sanatana Dharma,one may uncover shocking facts. Looks as though the Dravidian culture preceded Sanatana Dharma. But this theory goes out of the window because Tamil literature quotes Vedas,Puranas,Ramayana and Mahabharatha and these texts quote Tamil/s! One is stumped. Add to this the excavation of a million year old site in Chennai,where traces of advanced Tamil civilization is found. Poompuhar sites push the date of Tamils by 30,000 years. More sites,numbering 293 in Vaigai River near Madurai confirm the antiquity as found in the other sites mentioned above. My view on Brahui being present in Balochisthan is due to the presence of Tamils in these areas when kings from Tamil Nadu invaded them. There are three kings who have been credited with invading North,not to speak about those who had friendly relations with the people of Sanatana Dharma. They are, Aryavarman, Ariyappadaikadantha Nedunchezhiyan Imayavaramban Neduncheralaathaan. I am researching on who the first Tamil king ,who invaded The North of India. I am reproducing some theories,one of which suggests Dravidian Invasion of India. Shall examine this theory as well later.
