Reality Retcon

""I reckon there's been a lot of chaps in our position, down across the years. Makes you wonder, doesn't it? Makes you wonder how much of the world is true.""

- Fred Abberline, From Hell

Writers never let the facts get in the way of a good story. If reality doesn't fit the plot, it can be changed. History and myth are the most common targets of this - it's much easier to convince the viewers that a 9th century pope was actually a woman disguised as a man than that the current pope is female.

When this Reality Retcon is a story premise Plausible Deniability is generally the aim, but the retcon remains a clear, deliberate, and direct contradiction of generally accepted facts.

Common examples are:
 * Ancient Astronauts: Gods or legendary figures were really aliens.
 * Ancient Conspiracy: All history is just a charade, staged by a secret society.
 * Beethoven Was an Alien Spy: An historical character had a secret life.
 * The Gump: An original and/or unlikely character is The Man Behind the Man causing well-known historical events.
 * Julius Beethoven Da Vinci: Many historical characters were all the same long-lived person.
 * E.T. Gave Us Wi-Fi: The development of human technology got a boost somewhere from little green men.
 * Historical In-Joke: history is rewritten for the sake of a single joke.
 * Retroactive Legacy: Pretending that a given debut work is actually the latest in a longer series going back years.
