The myth

What is very appealing to the whole Star Wars universe is that it is all presented as a myth. Several hints were dropped in the original trilogy, and others in these current sequels – the Jedi and the Sith are nothing else than a legend, a myth whose origins were lost in time.

Rey is the one who asks who is Luke Skywalker and who says that she believed he was just a myth. Maz Kanata, as well, is also a mythic creature, who has lived for so long that she is became a pirate of legend. Han Solo’s Kessel Run is also a thing of legend.

The deleted scene showed Rey actually asking who Luke was. And while it didn’t add anything (and, by the way, didn’t make sense in the final cut of the movie), it would have once again consolidated the idea that everything is happening, long time ago in a galaxy far, far away.
