Simultaneous appearance of written language and common man

In http://EvC Forum: Peg Topic Index -->EvC Forum: Peg Topic Index (okay I could use help changing how the link looks) Peg indicates that fully formed writing systems appear at the same time as modern man: I asked Peg for evidence to support her position and received a long answer about spoken languages. I'd like to ask Peg again to provide evidence that supports the idea that modern man appears simultaneously with written language.Peg, the difference between written and spoken language is that written languages leave evidence. I've stated that there is a smooth transition from proto-languages through written languages a fact that's easy to infer on observation of the evidence. Pictures turn into ideograms and eventually into written languages, not suddenly but gradually.Could you please show me the correlation of the appearance of modern man and fully formed writing systems that is consistent with either creation or with survival after the flood. When I look all I see is unrelated writing systems appearing in different areas demonstrating a smooth transition from proto-writing through complex writing systems.
