Is someone hiding aliens?

“We don't think so. Many Americans (and quite a few citizens of other countries) are convinced that extraterrestrials may be buzzing the countryside in their spacecraft, or occasionally alighting in the back yard to abduct a few humans for breeding experiments.

This would be of enormous interest and importance of course, and (in our opinion) impossible to hide, particularly if it's happening internationally. The presence of aliens on our planet is not something you would want to hide: it would be the biggest science story of all time, and tens of thousands of university researchers would be working away on it. However, despite the popularity of aliens on both silver and phosphor screens and a half-century of UFO sightings, the lack of credible physical evidence has made it difficult for serious scientists to believe that UFOs have anything to do with extraterrestrial visitors.”
