By this logic you can discredit anything people see. People commonly see cows. But, people also hallucinate orbs in the sky, so cows don't necessarily exist, do they? So, back to my original point, if we focus on the relative number of sightings of two things, and exclude random other things, there's still a huge number of sightings of "shiny metal objects in the sky" compared (relatively) to "flying spaghetti-and-meatballs monster in the sky".
