"Pagan" Texts (Mesopotamian & Egyptian) — c. 2400 – 2100 BCE
If we define "pagan" in its broadest sense (ancient polytheistic religions outside of the Abrahamic faiths), these are the undisputed oldest religious texts in human history.
Hebrew and Greek texts emerged roughly around the same era (8th to 6th centuries BCE), long before the Romans compiled theirs."
