The statement of centre defies all logic. There is a story (even if I agree with centre that it is imaginary) that talks of a sethu build between India and Sri Lanka. Now NASA brings to us photgraphic evidence that such a sethu exists. Does this not calls for a rational and not India style sickular examination of the rama sethu and its association with ramayana... The sethu itself is a massive proof that the story of ramayana has elements of truth associated with it... May be the authors of ramayana took liberties and the bridge was already there that was used as a guide by the armies of ram that sailed along the structure ? Maybe they actually used the structure itself by reinforcing it at places ??
