This Ramar Sethu has been shown to be the pre human structure, called tombol, a sand deposition due to natural process. The Geological Survey of India ruled out its being the manmade (or monkey made), construction. Same way the inference from NASA satellite pictures is that it is due to sedimentation of clay and lime stone. It is tombol in NASA language, connecting one land with another, and that it is from times when human habitation is impossible. Beware of these anti social elements who made modern days life toughs mothers are delivering babies on roads like MONKEYS.
