that would suck..do pictographs count as written language? If not, i would say we'd use those. Petroglyth's coem to mind, they were around before cuniform
If you are including petrolgyphs in it, since one could say they led to heiroglyphics..which led to probably early lettering (depending on your wrttien language these days..some use lettering, some use a type of heiroglyph)
If you ara including those, I think we would would use art an dmaybe archetecture, something like that.(when there's a will there's a way)
Or maybe, telling stories to be handed down form one generation to another.."myths"..told in an entertainign way, so at to be remembered and passed on.

If I was a boat, would I be in a fleet of five or three?
