Ram Setu is a must watch movie for Indians and people of Indian origin. It is our cultural heritage and a matter of pride for every Indian. Regarding Ramayan; Ramayan is written with lot of details, place where lord Ram was born, position of planets, stars. Details about every event of his life, cities, forests where he went. Lanka, which is present day Sri Lanka, Ravan, Ashok Vatika and so on..Simply stories cannot have such detailed description of all the events. It is written in Ramayan that Ram Setu was built by engineers Nal and Neel. Why are we underestimating the engineering marvel from them by simply saying it is a natural formation? I respectfully ask people who are saying so, what scientific data do you have that Ramayan is not true and Ram Setu has nothing to do with lord Ram?
If tomorrow there is natural calamity (say a meteorite hits earth) and humans cease to exist, the new generation of species that come on the planet might think that we humans were scientifically and technically not savvy. What proof will we provide thousands of years later that we were tech savvy ?
There were some exaggerations in the movie (under water suite etc) but the overall movie has a good message. When historical structures like Qutub Minar, Taj Mahal, India Gate that are mere monuments are preserved, then why not Ram Setu bridge?
