Answer:
Yes, there was literature, but it was all oral literature.
Explanation:
This is because primitive cultures did not develop writing systems. The first writing system emerged in Sumer, around 4,000 BCE, and its initial purpose was not to write literature, but to make accounting records.
Primitive cultures simply did not need writing, and they also considered oral literature to be a high form of culture. There were people specialized in telling stories, who could memorized the equivalent of thousands of written pages.
