This reminds me so much of the Raglan hero archetype rank: https://en.wikipedia.org/wiki/Rank–Raglan_hero_archetype

So many stories, many people believe are true and build whole religions around, are really just repeated stories with many details changed to fit the local culture and traditions.

It's crazy so many of the world's politics and problems stem from what might actually just be the same story said in a different way... or even of a fan fiction on top of existing fiction.
