Actually the Star Wars Galaxy is our galaxy, and we never see the Earth in Star Wars stories simply because our planet is in the Unknown Regions, and therefore it was never discovered by the Republic or by all the other galactic governments. The classic intro “A long time ago in a galaxy far far away” is NOT written from our point of view, but from the point of view of an extragalactic (extra-Milky Way) civilization that lives in a very distant future.

Also, TCW, The Bad Batch, Rebels, Rogue One and The Mandalorian are TV series and movies, exactly like in our real world. I mean, what really happened during the Clone Wars and during the Empire Era is told in the Expanded Universe books and comics, while TCW, The Bad Batch, Rebels, Rogue One and The Mandalorian are simply TV series and movies created within the Galaxy itself, to tell in an entrataining way the events of Galactic history. These series and movies contradict the real history because they are entertainment products, and therefore don’t have to be historically accurate. These series and films were created by the Galactic Alliance between the end of the Yuuzhan Vong War and the Sith-Imperial War of the Legacy comics. They are the equivalent of “Inglourious Basterds”, “Vickings” and “Rome” in the Star Wars universe, that is, they are series and movies that are set in times that have really existed and tell some real stories, but they mostly contradict the real history because they’re entertainment series, and therefore they don’t have to be historically accurate and meticulous.
