[Star Wars] Why do people in the Star Wars universe think that the Jedi are myths or use the term "the legends say..." when there was an entire branch of the government run by Jedi less than 20 years ago?

Is 20 years even long enough for something to fall into legend?

Less than 10,000 jedi at their height of power. That's barely anything in a galaxy of trillions to quadrillions. Jedi didn't leave the core republic systems often and rarely visited planets that weren't of importance to the republic. Palpatine ran a massive smear campaign and destroyed nearly all evidence of the Jedi after order 66. 

Not everyone knew what jedi were or did beyond drunken tales told by spacers in bars even at the height of their power. They were reclusive and rare to the point that even most senators on coruscant had never met or seen one. Let alone some hick kid on the edge of civilization.
