What is the first written language?The Sumerian language is one of the earliest known written languages. The "proto-literate" period of Sumerian writing spans c. 3300 to 3000 BC.

It makes sense that humans began a form of abstract writing about 3000 years BC.

Could be way earlier but supposing this is factual, humans could still have taken more than just a few thousands of years to develop writting skills or a writting system.

Though I have not gone into much research, it is certain that humans could not have existed for such a short period of time.

what makes you say that"it is certain that humans could not existed for such a short period of time"?
