In the outline and sample chapters for Robert J. Sawyer's cancelled novel and therefore non-canon Alien Exodus, Earth is revealed in a flashback story to be the original home of the Human species. A group of refugees and dissidents from Earth commandeer a spacecraft and flee a computer-controlled society (a society which, apparently, will later become the setting of George Lucas's first film, THX 1138). They accidentally travel backwards through time and through intergalactic space to arrive in the Star Wars galaxy.
