Reason No. 11 not to believe UFOs are aliens

I had recently sent my list — “10 reasons you shouldn’t believe in UFOs” — to Bad Astronomy blogger Phil Plait, because he had raised a valid objection to the way many in the mainstream media treat reports of unexplained sightings. Plait was gracious enough to post my list to his blog yesterday. He also added another great reason to be skeptical by noting that those who spend more time than perhaps any other group looking up into the sky rarely if ever report seeing UFOs.
