Dr.Satya..this article of yours is very well written and explained,i just wish & hope in misery that our Govt. atleast do some research on our ancient history. The problem here only is research, which as u mentioned cant be done on something which existed millions of year ago but I personally feel, if it is tried it wont be a surprise if some sort of evidence come up. In time of Ramyana Valmiki mentioned about Plane...n dat too a Vertical take off and landing(pushpak) which in modern times humans r trying to perfect.Valmiki Mentioned bout position of Adam's Bridge,Sri lanka...He dint had any kind of Satellites to tell him n position of those places n if im not wrong...he wasnt present in any of those places. He was writting Ramyana thousands of Km's away from the places he mentioned.
