How old is Tamil language?

Tamil is one of the longest-surviving classical languages of India.[11][12] A. K. Ramanujan described it as "the only language of contemporary India which is recognizably continuous with a classical past".[13] The variety and quality of classical Tamil literature has led to it being described as "one of the great classical traditions and literatures of the world".[14] Recorded Tamil literature has been documented for over 2000 years.[15] The earliest period of Tamil literature, Sangam literature, is dated from c. 300 BC until AD 300.[16][17] It has the oldest extant literature among Dravidian languages. The earliest epigraphic records found on rock edicts and 'hero stones' date from around the 3rd century BC.[18][19] About 60,000 of the approximately 100,000 inscriptions found by the Archaeological Survey of India in India are in Tamil Nadu. Of them, most are in Tamil, with only about 5 percent in other languages.[20] Tamil language inscriptions written in Brahmi script have been discovered in Sri Lanka and on trade goods in Thailand and Egypt.[21][22] The two earliest manuscripts from India,[23][24] acknowledged and registered by the UNESCO Memory of the World register in 1997 and 2005, were written in Tamil.[25]
