Drawing, not writing. Drawing is a form of expression and the exchange of ideas, true. However, i beleive what the civ people mean by writing is the exchange of ideas through literature by using a refined language, and they can't do that without an alphabet of some sort. People who used pictures to communicate ideas weren't making use of a particular language, thus the ideas they tried to convey were vague. Writing is a much clearer form of communication provided that the reader understood the language it was written in, and could recognise the symbols of it's alphabet.
