The description of Ram Setu is present in our centuries old epics. That detail hasn't come overnight, so what proof this ASI requires. Are they so unaware that India was invaded badly for thousand years by muslims and under such difficult times who can keep history. Keeping record of the past is a new trend came with britishers, otherwise Hindus have never thought of keeping any record. They don't decorate their graves or kabar. When they don't keep record of their parents memories which is right also, why should they keep record of centuries old books which is practicsed in Indonesia and Malaysia in the form of play. Even a muslim want his son to be like Lord Rama
