I assumed that Indians,educated included are aware of these references. Thanks to western education and doctored History of India,where everything worthwhile in India was/is being dated only after the birth of Christ,despite overwhelming archeological evidence and foreign literary works. I have also written that Poompuhar,excavated sometime back,is dated around 30,000 years ago and the Period literature Silappadikaram mentions Vedas. And there is a million year old archeological site in Chennai ,India that had an advanced Tamil civilisation. The earliest Tamil grammatical work of Tamil mentions Vedas and its author Tholkaapiyar declares himself to be a Brahmin well versed in the Vedas. And I have written many articles on this subject of the intimate relationship between Sanatana Dharma and Tamil/s. However there have been quite a few mails asking me to produce evidence of Tamil being mentioned in Early Sanskrit Texts.
