The ordering was made to make it easier to find the places on the map not because of any progression of civilization I personally would prefer alphabetical sorting For the names of placemarks I prefer the ancient names since this is an article about ancient sites with alternative names and modern names given in parentheses Which cities in the list have not been located I will change location uncertain to inexact coordinates to reflect that onlymy coordinates are not exact as I prefer and not the location of the site as such is uncertain Eg Kish is somewhere in the vicinity of the given coordinates but not in the exact spot But I am continuously refining the coordinates
