all ramayana places are true.one could see the caves in hambi,karnataka where sugrevan and his army were hiding fearing of vali,where lord ram visited them.similarly there are many places in india exactly matching names of places mentioned in ramayana. why ram sethu bridge exist only in between srilanka and rameswaram. why not between chennai to srilanka or from pondicherry to srilanka or from nagapattinam to srilanka.the truth of bridge astonish everyone exactly matching the description given in ramayana. valmiki did not sit in satelite to write this story from orbit but without visiting all these places,entire episode of ramayana was visulised in his eyes due to divine grace.hence he could write with exact locations,timing and happening ect which valmiki told lord ram himself in the presence of lava kusa,sons of lord ram for 28 days.
