Then why is the script different boss.<quoted text>
dont write your opinions please provide proofs. kannada,telugu,malayalam and tamil are no difference. tamilii + sanskrit = kannada,telegu and malayalam. all four languages share the same history bcos all are tamilii. the difference is like kanyakumari tamil,tirunelveli tamil,coimbatore tamil and chennai tamil. when tamil nadu was less affected by sanskrit other dravidian languages were verymuch affected.
European laanguages came from latin script is same.
Hindi, punjabi and bengali came from sanskrit script is same.
And I dont think kannada and telugu came from a language which has no diff between ka and ga ,tha and dha and many more like you cannot write "anyayam" in tamil as it is,it can only be written as "anniyayam".
What I think is that the four main south indian languages came from some other language
