Second Great Tamil Tsunami 13000 BC Chera Dynasty Silappadikaaram 9600 BC?

Therefore,both Ilango Adigal,Cheran Senguttavan may be anti- dated from the present Third century BC, to 11600 CE.

And the Tsunami of Sangam priod,the Second one,which Silappadikaaram mentions must be earlier to 15,000 years ago.

First Sangam-5000 -4400= 600 BC

Second Sangam-600-3700=3100 AD.

* For a language to develop and to attain highly complex Grammar and Classical Literature the language should have evolved at least 1000 years earlier.

** These dates agree with the dates of Ramayana.

So Tamil language should have been used at least by 4000BC
