I think this issue is too old for any interest, just my 2 cents. The chief minister of Tamil Nadu and Government of India are bent upon destroying the age old Ram Setu as it helps in economic progress. Agreed, nothing wrong with that, but if Rama is considered god by many people in India and we celebrate atleast 1 or 2 festivals each year to celebrate the triumph of good over evil (Rama killing Ravana) across the whole of India, wouldn't Ram Setu become a national symbol worth preserving.
To draw a parallel, in USA alcohol is not sold on Sunday’s till 12:00PM. This is done to honor people who go to church. There is no science involved to suggest no alcohol till 12:00PM on Sunday’s but it is honoring something that most people in this country at one point believed in. I am sure this is an economic hit for many but is pretty strictly implemented.
Scientifically speaking may be Ram Setu was never built by Rama and it is a natural formation or for that matter Rama never existed. But what matters is it is imbibed in our culture and it is part of our identity.
Science alone should not rule our lives but we need a combination of science, faith and belief.
