I was wondering when writing first began. I believe stele tablet with symbols from sumeria is first known example of any kind of writing correct?? Do you think adam & eve had any capability of any form of writing?? Were all writings primarily symbols and heiroglyphs like found in Egypt during Moses time?? Just a question i never really looked into before.

I did a google search of “When did writing first began”. I stumbled upon the Wiki article:
Wiki - History of writing
Historican - History of writing
This is from the Wiki article:
