Even if that's correct--which it would likely be, since a literal translation wouldn't be meaningful to a modern audience--the corollary problem is that the very idea of writing stories that were stories, versus oral myths/religion, or more purely informative, didn't really exist at this time. I don't think that we even have evidence that theatrical entertainment existed 2800 BCE; the golden age of Greek plays was around 700 BCE, which is a solid 2000 years later than this was purported to have been written.
