It is difficult to determine the exact oldest historical fact, as much of the information from prehistoric times has been lost or is still being discovered through archaeological excavations. However, some of the earliest known recorded historical events include the Sumerian King List, which documents the names of Sumerian kings and their reigns, dating back to around 2100 BC, and the Egyptian Palermo Stone, which records the names of early pharaohs and significant events from around 3000 BC.
