But hey, that's just a theory, a film theory!

I believe I have solved the Star Wars Palpatine problem as he coming back meant Anakin didn't kill him which makes everything confusing; Because the events in the recent Star Was movies are 50+ years into the future from 6, I think at one point, time travel was used by the remnants of the Sith to save Palpatine, address the situation to him, and for him to be back to life
