I think that the author has not made any Scientific Analysis. Although I am a practicing Hindu and I think this article is merit-less. Take for example the statement : "The scientific interpretation of the photographs of the remains of Adam's Bridge (Ram Setu) taken by NASA's [Images] Gemini-11 spacecraft in 2002, reveals that this ancient bridge linking India to Sri Lanka [Images] was manmade, and it was dated to be at least 1.75 million years old."
Did he site any references of this alleged Scientific Interpretation? No peer-review of this! I think that the author and in-turn rediff did a poor job on this article.
