US TV show promo claims 'Ram Setu' is man-made
The 50-kilometre chain of limestone shoals connecting India's Rameshwaram and Sri Lanka's Mannar Island, known as 'Ram Setu' in Hindu mythology, is man-made, according to a promotional video for Science Channel's 'What On Earth?' show. It claims that sand formations dating back 4,000 years "may be natural" but the limestone rocks on top of them aged 7,000 years are not.
