The newly found ruins of lost city Dwarka tells a different story they could be as old as 10,000-12,000 years old by some estimates that too a fully developed port city....
that makes it the older than 5000 years to civilizations like IVC....
N not just these ruins we have got so many proofs of epics like Mahabharta n Ramayana which r spread all over India n most people don't even know about them...
Like recently i went to visit our Kul devi temple which is some 200-250 km from my place n there was a place near about 50 kms ahead of that temple which is said to have been visited by Pandavas during their exile there is also a very deep kund (something like a big swimimg pool) that is said to have been created by Bhim, even the king of the place of our Kul Devi has its name in Mahabharata war......
So likewise there r many places all over India which shows link to our Ancient civilization but not much research is being done even Dwarka was discovered during some pollution check test....
