How come the Seven Wonders of the Ancient World are all located in or around the middle east? It is quite obvious that the ancient civilizations was highly developed here, but surely there were other civilizations at that time that could build something magnificent. Didn't east/south east Asia or South America have quite developed civilizations for that time?
