Difference between "mythology" and historical "facts"?

In this video, a monk tried to draw a distinction between "mythology" and "history facts" ... [Ajahn Sujato - Buddhist Mythology - The Sacred and the Profane - Part 3](https://youtu.be/QgSj6Wa9vPA) ... saying that "Mythology" just has a community (identification) purpose. Yet my person's thought was, "and how is that different to 'factual' history (aside that it faster changes)?" How can "mythology" ([Anussava](https://dsalsrv04.uchicago.edu/cgi-bin/app/pali_query.py?page=45)) , and "history" (perhaps thought as [Itivea](https://dsalsrv04.uchicago.edu/cgi-bin/app/pali_query.py?page=119)?) , be seriously distinguished, if possible? And how should the past be seen, grasped, in accordance with the path, practice? What kind of mythology, history, and *anussati* (bringing into present) is conductive for one's way, toward long-time happiness and beyond? *(Note that this is not asked for trade, stacks, exchange or entertainment, but for good undertakings toward release from this wheel)*
