No, the small independent city states of Greece are very much a factor of the geography in which that society evolved. Compare this to the hittites who were divided between the northern lords and the southern lords by a mountain ridge, and how their civil wars always fractures along this geographical feature, or the Babylonians and their chaotic society influenced by the irregular and chaotic floods of the tigris and euphrates, or Egypt and their strong national identity influenced by the steady, predictable Nile which united the entire country and facilitated their identity as egyptians, rather than as citizens of their particular city.
Geography is everything when influencing how a society will develop, especially one as simple and primitive as this.
