History is quite fascinating. Recent researches around the world have thrown up powerful evidence that has changed our knowledge, what was once thought a myth had sound provable basis. India is perhaps 200 years behind in discovering it's past. Short-term thinking means that such work is not approved by politicians.
Like the recent finding of the city of Troy, which was thought a myth, it is with proper research and investigation that archaeology will find positive evidence of Ram. As we find with other ancient stories, that previously were taken as false, there is always truth behind stories that prevail. The story of Ramayana has to have a basis, and in terms of factual information has as much, if not more, than religious books of other faiths that are not questioned.
