Agreed. If they were able to prove that the body is that of the actual 'John the Baptist' written about in various religious texts... it would be a very important discovery. It would lend a measure of validation to the historical truthiness of said texts so far as the people mentioned in them having been real people, rather than fictional characters. Unfortunately, there is no way to prove it.
Either way, it wouldn't serve as evidence to support any of the supernatural claims of Christianity, only as evidence that one or more of it's founders was a real person.
