Sounds like a wise and reasonable suggestion, to me.
If all the real UFO's disappeared from the Earth today, There would still be as many sightings tomorrow.
Although, as I pointed out there have been less sightings, since the UFO KOOK's have become preoccupied with ManMade Globaloney Warming.
Why don't you just use your Ouija board to discover where their home planet is? Perhaps a fuller name for UFO believer's should be: Unidentified Flying Objects of Overactive Lunacy, "UFOOL" for short.
And since when is being sensible "holier than thou?"
