There miskate done by UPA Govt. Ramasethu may not be holy place but it is historical place.
When 5000 year back valmiki writen Ramayana, he mention that Rama with Vaanarasena made a Sethu (Bridge) on Sea (Samudhra) to reach Lanka. It is Epic, the construction of sethu in sea is may be possible or may not. BUT PEOPLE BELIEVED.
After 5000 years, (I thing 2 Years back)Our great scientist discover the Adam Bridge (We called as Rama Sethu), people feel wonder, Yes there is one more witness /base for Raamayana.
When Epic Raamayana's time Sethu and Adams Bridge is if same who knows.
In 5000 years back , who knows what is sea level, Rama sethu is may be visible in three to four feets below the sea in that time, may be vaanarasena made stone on Admans bridge just for walk, who know what happen in those days.
BUT IT IS TRUE, IF KING RAAMA IS TRUE IN 500O YEARS BACK, HIS JOURNEY TOWARDS LANKA IS TRUE, THEN HIS SETHU IS TRUE.
