My dear MR. For your reference, whatever happened during times of Lord Rama were recorded in his time by Saint Valmiki. This happened hundreds of years back when Mohammedans or christ followers did not know how to read and write. After hundreds of years later there was a visitor from Western country who had defined about India as a person if starting to walk from Kanyakumari in his childhood will reach Kashmir in his old age. Just imagine Saint Valmiki has written this by imagination, How he will be knowing about each and every place on the way from Kishkinda upto Lanka which is a island. So each place u visit where Lord Rama has passed even today there are monuments like Gokarna where he worshipped Lord Shiva and other so many things. If you want contact me and I will give details personally.
Regarding the government claim of natural formation with Nasa pictures which can fool nobody. Saint Valmiki can never had seen through satellite. And if formation is gradual then this should not have existed thousands of years back.
So instead of questioning and losing the history, let us realise and save this great monument.
Science still is in very young age. They have to go a long way. Recently they were able to discover Dwarka and understanding about Rama it may take hundred's of years. So let us wait.
