Who gives a damn what you believe? Go to hell for all I care. If people of India believe the Ram Sethu then that is all that matters.
Stop thinking that if you don't believe it then others must also follow you. Only a moron like you thinks that. If people believe in Ram Sethu so be it. Lucky for you Hindus don't issue death fatwas like Muslims do. Can you imagine that? So be appreciative and be respectful for those that have faith.
