All the cultures of the world have some sort of records,legends on the Great flood that inundated the world.
These details are found in the Bible, Hinduism,Jewish History and Zend Avesta.
These details are also found among the illiterate ethnic groups in the form of ballads.
Tamil literature deals in detail about the great flood,Kadal Kol.
Tamil Epic, among others, Silappathikaram deals exhaustively on his subject
Portions of Tamil Nadu were submerged under the sea including the Then Madurai, the Madurai in Tamil Nadu belongs to a different period.
Bible speaks of One flood.
Considering the historical proof found and the number of references Tamil and Sanskrit references seem to be more authentic and they include the one mentioned in the Bible.
We shall see how these Floods happened and their approximate dates.
“ca. 200,000 to 50,000 BC: evolution of “the Tamilian or Homo Dravida”
ca. 200,000 to 100,000 BC: beginnings of the Tamil language,000 BC:
Kumari Kandam civilisation20,000 BC:
A lost Tamil culture of the Easter Island which had an advanced civilisation.
Lemuria submerged6087 BC:
Second Tamil Sangam established by a Pandya king 3031 BC:
A Chera prince in his wanderings in the Solomon Islands saw wild sugarcane and started cultivation in Present Tamil nadu.1780 BC:
The Third Tamil Sangam established by a Pandya king7th century BC: Tolkappiyam (the earliest known extant Tamil grammar)
Of the three Floods, the Mahabharata refernce to Chera King ,Udiyan Neduncheralathan having participated in the Mahabharata wa along with Pandya King probably relates to the Second Sangam period as the first Sangam period was wiped out when Lemuria sunk.
This means that the earliest reference to Tamils is from Mahabharata which is dated around 3000 BC.
( However there is enough evidence in the Puranas and the archeological finds in Tamilnadu indicate that the Tamil Culture had thrived during or even before the Vedic, Sarasvati Valley civilization)
The third Sangam was established by a Pandya King and his lineage may be traced back to the Vedic period.
“And, O Yudhishthira, in the country of the Pandyas are the tirthas named Agastya and Varuna! And, O bull among men, there, amongst the Pandavas, is the tirtha called the Kumaris. Listen, O son of Kunti, I shall now describe Tamraparni. In that asylum the gods had undergone penances impelled by the desire of obtaining salvation. In that region also is the lake of Gokarna which is celebrated over the three worlds, hath an abundance of cool waters, and is sacred, auspicious, and capable, O child, of producing great merit. That lake is extremely difficult of access to men of unpurified souls. Mahabharatha 3:88
And similarly, Pandya, who dwelt on the coast-land near the sea, came accompanied by troops of various kinds to Yudhishthira, the king of kings. Mahabharatha 5:19
Steeds that were all of the hue of the Atrusa flower bore a hundred and forty thousand principle car-warriors that followed that Sarangadhwaja, the king of the Pandyas. Mahabharatha 7.23
In return, Malayadhwaja pierced the son of Drona with a barbed arrow. Then Drona’s son, that best of preceptors, smiling the while, struck Pandya with some fierce arrows, capable of penetrating into the very vitals and resembling flames of fire. Mahabharatha 8:20′
Add to this the Bhagavatham stating that the Ancestor of Lord Rama, Satyavrata Manu having migrated to North with two sons to establish a Kingdom in Ayodhya.”
This is a clear indication of the culture from the South moved to North , to Sarasvati Valley and later Indus Valley.
Then there is the Tamil script being found in the Mohenjo-Daro.
One batch of migration from the south took place towards the Sarasvati .
What about the next?
We have references about the Arctic the Home of the Rishis and Vedas, Lemuria and Atlantis being one.
We shall examine in detail
