No doubt about it .Otherwise how to explain that the Protrusions on the Indian side is excatly joined to the Protrusion on the Lankan Side?
Also this is the shortest possible distance between the two lands.
Also ,according to reports that came in Rediff in July end,the chemistry/constitution of the boulders found on the Sethu does not represent that of the surrounding.
Kilometers of Boulders laid to connect two natural protrusions of Inia and Lanka with the least effort principle(ie shortest distance) connecting either side in AN ENGINEERING PRINCIPLE that ONLY HUMAN BEING CAN THINK OF.
Hence the most Scientific Conclusion:Sethu is Manmade.ANY MUDDLE HEADED CHALLENGERS ANY MORE???
