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 e g kish is somewhere in the vicinity of the given coordinates but not in the exact spot but i am continuously refining the coordinates
