Because either Rey’s parents were on that departing ship or they’re dead and buried on Jakku. It can’t be both.
And Kylo can’t be trusted.
I already asked this, but are we really sure we see Rey’s parents leave in that ship? Maybe it was just a random ship and Rey imagined her parents were in there, because that would make it easier for her.
Given Rey’s response to Ben, it’s clear that Rey has maintained a myth about her parents in her mind. Why can’t she have manufactured a memory? Not that unrealistic. Indeed, there are still Star Wars fans who maintain that Luke’s first go at the grappling hook missed when SW first hit theaters.
