Of course it is, among other timeless plots laced with sciency-things. "Star Wars" has a particularly aristocratic Space Western origin, since the writer of "The Empire Strikes Back," Leigh Brackett, also wrote a couple of classic John Wayne movies ("El Dorado," "Rio Bravo").
She was also a very successful science fiction author in the 1930s. The "science" is dated - nobody thinks humans could survive on Mercury anymore - but a good story is a good story, and a good story can be made into a successful movie.
Star Wars is a story about a farm boy, an old wizard and a pirate who rescue a princess from an evil sorcerer in an impregnable castle. The sci-fi part is just window dressing.
Never cared for sci fi but I’m starting to feel a little embarrassed that I’ve never seen ‘Star Wars’ or any of it’s progeny.

She only wrote one. Rio Bravo received a “haircut” and became El Dorado, which received a “haircut” and a few Civil War scenes and became Rio Lobo.
Same script for all three, same plot line, same actor John Wayne.
Fire(d)fly is more space cowboys than Star Wars.
Gene Roddenberry sold the idea of “Star Trek” to NBC as “Wagon Train to the Stars”. It’s not unheard of.
