I think someone said it was The Epic of Gilgamesh, but I could be wrong. This should probably be moved to The Lounge.
I doubt it exists now. Probably been destroyed thousands of years ago. Egypt has some old stories written on the walls, also, there were mayans; ancient China. Plus, there are locations of even older settlements. Including some here where I live (several hundred kilometers from my location), some ten to twelve thousand year old ones, but as far as I know they didn't know how to write. Atlantis... if it existed it must've had something somewhere written. Anyone know where the Atlantis myth began?
Atlantis began with Plato..without Plato we would not have heard of Atlantis. I might be well wrong. In orther to figure the earliest written piece of literature if to figure spoken language to be recorded meaning spoken culture.
I think that is correct in terms of works that still exist in some form today. There are other Sumerian texts that might be a little older, but the uncertainty around dating them puts them in roughly the same ballpark as the Epic of Gilgamesh.
For a long time considered the oldest Dutch sentence, round 1100: Hebban olla uogala nestas hagunnan hinase hic enda thu uuat unbidan uue nu [Have all birds started their nests except me and you so what are we waiting for?] However, the oldest is from round 800: Gelobistu in got alamehtigan fadaer [Do you believe in God the almighty father].
I don't know about the other categories, but it's argued that Murasaki's The Tale of Genji is the first novel.
