As religious groups protested on the grounds that the bridge was built by Lord Ram more than a million years ago, project officials and the shipping ministry had said Nasa documentation showed the linked formations were a natural phenomenon and %u201Ctheir occurrence is not evidence of any human activity.%u201D
But now a National Aeronautics and Space Administration (Nasa) spokesman says the agency has made no official statement over the origins of the Adams Bridge, a coral walkway between Tamil Nadu and Sri Lanka slated for dredging to shorten shipping routes.
So we see, NASA also poured water over the claims that the bridge was a natural formation.
Let us now keep NASA away from this , till they come up with more fantastic ideas, none of which can be 100% true, given the fact that their data is limited.
