Just because some self proclaimed historians with the limited tools and knowledge could not prove does it conclude that Sethu was not constructed as per RAMAYANA.Can everybody say that what scientists establish today is FINAL and thats all.Tomorrow when our knowledge and tools improve knew things will come into light. The Lazy government Officials can not prove or show Documents of Thousand years back, how they can prove a thing of "TRETAYUGA". They could have said it is not practical to prove rather than telling it is not SETU. On what proofs "TAMIL" was declared as a very ancient Language? Just for Political gains . P S N ACHARYULU
