on Ram sethu bridge is visible to eyes from the start to end which you can see both from sirlanka and india and also from areoplane.if it is natural,it will not be chained in a line from start to end.ram sethu name figure in ancient tamil scriputres like manimekalai and in purananuru besides in alwars pasarams.during the time of ramayana,sanatana dharma was prevailing with vedas occupying important role and hence even ravana is an expert in sama veda and he was true devotee of lord siva and have knowledge about dharma.but for his abduction of sita devi, he was even admired by hanuman on first seeing ref sundra kanda.becouse he knew dharma,he allowed vibhishna his brother to join with lord ram and he did not harm vibhishna for deserting him. just compare mohul leader aurangazep,just for the sake of power and his brothers desire towards hinduism, aurangazep killed all his brothers and sentensed to jail his sister.so imagine the great difference between hinduism and other religions.
