Before anyone can point fingers, let me say that that Im very much a believing Hindu. You can call the formation a bridge, or you can call it an undersea formation. Even if it was a man-made bridge, is there proof that it was the very same one constructed by the vanaras? The question than is the same, Krishnadevaraya of Vijaynagar could be holding the same beliefs and the British in their 1767 survey must have just gone along with the nomenclature. Bear in mind that if the Ramar Setu is history for us, it was also history in the 16th and 18th centuries. We have no way of verifying if they had any concrete proof for their belief in the Ramar Setu too. So citing these elements as evidence is grossly inadequate. Secondly also look at the loss that India suffers because we lack our own port. Sri Lanka pockets a huge sum as a deep sea harbour. China wants to build a base in the Maldives and even otherwise our ships take a whole day more to cross over from the Indian ocean to the Bay of Bengal since they take the Sri Lanka route. Lets not fall prey to blind belief and halt development.
