// the Clear Conclusion is that They are parts of Rig Group of Vedas, and NachinarKiniyar’s Comment was made to show Tholkappiyar as Older, on a biased note.//
Why should Nachinaarkiniyar be biased? Clearly materials available to him are no longer available to us as many Tamil works of his time are now lost. What personal benefit did he get by saying that Tolkaappiyam was older? What is meant by you by saying "Rig Group of Vedas" ? Where do these terms appear in the Rig Veda: "Thaithriayam, Bowtikam, Thalavakaram and Saamam"? Where did PaavaaNar express this conclusion? It is clear that they were Tamil Vedas. Why would Tamil works refer to Arya Vedas?


//Now on Tholkappiyam’s dating. Paavnar first dated to 2000BCE and later brought down to 650 BCE. Much Widely Accepted Scholars such as L.Rasamanickanar and Tho.Po.Mi. said older of Sangam Collecctions and datings were around 200-300BCE.
Presently we have much Objective Research and Various Datas to conclude.//
On what basis are you saying PaavaaNar revised his Tolkaappiyam dating? Pl give us the citations, name of books, page numbers and dates of publication.
Who is L Raasamaanickanaar? (Is the initial correct?) What fresh evidence do the present day researchers on whom you are relying have before them that the older ones did not have? Why do you say "much objective research"? Why "much objective?"

// his son was Nediyon. As per Aham 116 this Nediyon was called “Nilantharu Thiruvin Nediyon”.//
What is the point that you are making?

// from end of Ist Cen.BCE, only from then on referring of MuVenthar starts and Tholkaapiyar says that once.//
What evidence do you have to say this?

//1. Late 3rd Cen. – 100 BCE, BT brahmi Tamil
So 50-100CE, must be the earliest of the dating for Tholkappiyam.//
No basis for this opinion!!

//As for as God name Shiva- we do not have Once Even in Sangam to Silapathikaram and Manimekhalai. And most of the time Sangam refers to Shiva- it is always as Veda Giver.//
You are contradicting!
Not all Sangam works and those written by individual authors of that period have been found. Many have been lost or destroyed. If a word is not found in Sangam works, it is not a basis for concluding it is not a Tamil word. The root of Sivam is Sivaththal; it is a Tamil word. The Vedics hated Siva and Linga worship.

// As for as books you referred were written when Indus Saraswathi river Civilisation remains were just been found and Misinterpreted as proofs of Aryan attacks on Dravidians are proved and today no Scholar of any Repute agree those.
To say Saraswathi valley proves Dravidian is far fetched and no basis as it stands today. I give a latest Opinion.//
The cited opinions do not necessarily depend on Aryan Invasion Theory. The theory is denied by some historians only because there was no evidence of any invasion in the M& H scenes. The cited opinions stand whether or not there was any invasion anywhere.

// He suggests that the weight of evidence is against it and that it should no longer be regarded as the main model of interpreting ancient India.//
What is the evidence and what weight are you talking about?

// the dating of the Vedic age ........................ of India has been shaken.//
The arya vedas are not as old as they made them out to be. That I agree.


// "The certainty seems to be growing that the Indus civilization was carried by the Vedic Indians, who were not invaders from Southern Russia but indigenous for an unknown period of time in the lower Central Himalayan regions."//
This conflicts with the DNA results now known and your summing is not worth our time. People with Indo-European male lineage blood picture have been found mixed with certain groups of Indian population. See the other threads in history section where this was discussed.

//The roots of the Words- Shiva are Purely Sanskrit Origin is accepted by Cambridge University Scholars, and the name appears in Rig and Samhitas and some of this has been given in Saiva Thread in History Section.//
Replies have also been given ad nauseam. You keep repeating.

// SivaLinga worship is never seen in any of Tamil Lit. of Sangam to Manimekhalai.//
I remember the word "kanthazi". What is it?


//. Where as we see Stone buildings from Asoka days itself in North.//
What buildings and where?

// sa cannot be start of words //
Only sow!! I have answered this before.


//India has One tradition that is Indic.//
Your Wishful Thinking and history revisionism is driven by your own indic ideology.
