I have , based on the available evidence, that there was a close contact between the Tamils and the rest of the world, specially with the Middle East ,South East Asia and Italy.
To cite a few archeological facts,
A Tamil-Brahmi script inscribed on a potsherd, which was found at the Khor Rori area in Oman, has come to light now. The script reads “nantai kiran” and it can be dated to first century CE, that is, 1900 years before the present. The discovery in the ancient city of Sumhuram has opened a new chapter in understanding the maritime trade of the Indian Ocean countries, according to specialists in history.
1.Lord Rama’s Chapel was found in UR, Iraq.*
2.A burial ground called as Nagar is fond in Syria. It is called Tel Brak now.
3.Idols of Rama,Sita and Lakshmana are found.*
4.Ancestors of the Syrians were the Halaf and Ubaid.
They date back to 6100 BC.
They had connection with the Tamils and this is reflected in the ruins of Nagar.*
These people traded with the Tamils.
”Naram-Sin traded with Meluhha (almost certainly corresponding to the Indus Valley civilization), and controlled a large portion of land along the Persian Gulf. He expanded his empire by defeating the King of Magan at the southern end of the Persian Gulf, and conquering the hill tribes to the north in the Taurus Mountains.
5.Akkadian’s( Forefathers of the Sumerians) Moon God was Naram Sin, Narasimha.*
6.There are repeated references in the Sumerian/Akkadian language to Meluuha.
The interpretation and location of this place is hotly debated.
Sumerian texts repeatedly refer to three important centers with which they traded: Magan, Dilmun, and Meluhha. Magan is usually identified with Egypt in later Assyrian texts; but the Sumerian localization of Magan was probably Oman. Dilmun was a Persian Gulf civilization which traded with Mesopotamian civilizations, the current scholarly consensus is that Dilmun encompassed Bahrain, Failaka Island and the adjacent coast of Eastern Arabia in the Persian Gulf.
The location of Meluhha, however, is hotly debated. There are scholars today who confidently identify Meluhha with the Indus Valley Civilization (modern South Asia) on the basis of the extensive evidence of trading contacts between Sumer and this region. Sesame oil was probably imported from the Indus River region into Sumer: the Sumerian word for this oil is illu (Akkadian: ellu). In Dravidian languages of South India, el or ellu stands for sesame”
7.Ancient Tamil Brahmi Scripts were found in Oman and Egypt.
These facts establish that,
The Tamils were an advanced civilisation by 2200 BC(Akkadian Empire)
The Hindu Gods and Goddesses were worshiped in Sumeria,
Names of Lord Rama and Bharata were found in the Kings List of Sumeria.
