People go over their heads on some archeological sites over a few thousands year old.
But in India, there are sites which are over A Million year old in India, like the one in Pallavaram Chennai.
‘Archaeologists have discovered India’s oldest stone-age tools, up to 1.5 million years old, at a prehistoric site near Chennai. The discovery may change existing ideas about the earliest arrival of human ancestors from Africa into India…
The Story of Attirampakkam.’
The Tamil Literature is over a Million year old.
‘Archaeological research has uncovered evidence of fossil remains of animals and primitive stone implements around the northern Tamil Nadu that could be dated to belong to around 3000,000 BCE.Humans in South India,
Tamil quotes Vedas and they in turn quote Tamil.These two are so interwoven it is difficult to determine which is earlier.
The presence of Sanatana Dharma in the Dravida Desa, that is south of the Vindhyas seem to be earlier than the one in the north.
Please read my Post on this.
The archeological finds, the temples in South India confirm this view.
Of the many tools to date the monuments, sites,Banded Iron Formation(BIF), of analysing the rock formation is one.
The other reliable tools include Astronomy,Carbon Dating,Etymology and of course Archeology.
The Arunachala Mountain in Tamil Nadu, this is also called Thiruvannamalai.
This mountain is referred to in the Puranas, a quote is provided below.
The Ithihasas, Ramayana and Mahabharata are old, they quote the Puranas, which are older.
And ancient Tamil Language also quote the Purans.
So the Puarans are ancient History.
This Purana states that the Arunachala is ancient!
‘Geological experiments in and around Tiuvannamalai have revealed that the rock (charnokite) which makes up Arunachala covering is older than 3.5 billion years old ( Geological Survey of India) and
Banded Iron formations around Tiruvannamalai area are thought to be about 3 billion years old.
(Mineralogy and chemistry of banded iron formations (BIF) of Tiruvannamalai area, Tamil Nadu,Journal of Earth System Science,Volume 98, Number 2 / July, 1989.)
It is thus evident that even scientific conclusions do place Arunachala Age to be beyond 3.5 billion years and perhaps the range would be 4.4 to 3.5 billion years old.
