An assumption of 99% false sightings is not a statistic. Statistics are analyses of measured data, not assumptions. To know the actual percentage of true sightings, you’d first have to confirm that some sightings are actually true, which would require some actual evidence of ghosts/aliens.
Consider the inverse for a moment: if ghosts/aliens don’t actually exist, then the percentage of false sightings must be 100%, not 99.9%. As long as you start with the assumption that there are some true sightings, you’re just starting with the assumption that ghosts/aliens are real.
