The conversation between human and AI assistant.
How were the Jedi forgotten in nineteen years? 19 years is a short time to become a myth between episodes 3 & 4.
I see. But what about Luke Skywalker? He was just a farm boy, how did he even learn about the Jedi?
According to the Star Wars canon, Luke's father, Anakin Skywalker, was a Jedi Knight before he fell to the dark side and became Darth Vader. Obi-Wan Kenobi, a former mentor of Anakin's, went into hiding after the Jedi purge and kept an eye on Luke, eventually teaching him about the Jedi ways.
