I mean seriously though, the idea that Luke and Han both were thought of as legends more than real people, and the look on Rey’s and Finn’s faces when they realized both were the people the legends said (and Han the legend was standing right in front of them) was a great part of the movie.
Oh definitely. I think it’s clear that none of the big three Rebels ever went into the public light very much. Leia was probably the best-known of the three but she kept being an underground resistance fighter, Han went back to smuggling (not a profession of publicity), and Luke was always secretive and then fell off the map after his failure with Ben. None of them were ever more than legends after Endor.
Plus the galaxy is massive. It’s not a shock that Luke would see the Jedi as legends having grown up on backwater Tatooine despite the order falling just before his birth, so it’s not shocking to me that the exploits of three people in a massive galaxy would be legends for kids like Rey and Finn.
