A civilization (or civilisation) is any complex society characterized by the development of a state, social stratification, urbanization, and symbolic systems of communication beyond natural spoken language (namely, a writing system).[2][3][4][5][6][7][8][9]

If I have understood this correctly the painter of the caves in France and the builders of Gobekli Tepe were not civilized.

So if a civilization were to develop using only mental telepathy then we would consider them not civilized.

Hmmm ...
