Ram was a historical figure and he probably did exist. The article is well reasearched and also its true that I can think of cities like Harappa and Mohenjo Daro with such planned cities... its inconceivable to think that such plans were instructed without the art of writing.... I dont care if Ram Sethu was manmade or not... but if it helps maritime operations to build a free passway in the water cutting down the time needed by ships i am all for it. When no conclusive proof remains no need to sit and wonder if ram existed or not for buildign the water channel....
