3 - An Examination of Claims that Extraterrestrial Visitors to Earth Are Being Observed

Summary

Many members of the general public, and some academic scientists as well, maintain that at least some UFO sightings result from the activities of extraterrestrial visitors. Recent polls show that approximately 57% of the public believes that UFOs are ‘something real’ as opposed to ‘just people's imagination’. The figure rises to 70% belief for those who are less than 30 years old (Gallup, 1978), and have thus lived their entire lives in the age of television. UFO belief is not found predominantly only among the uneducated. A 1979 poll of its readers by Industrial Research and Development magazine shows that 61% believe that UFOs ‘probably or definitely exist’, a figure that rises to over 80% for those applied scientists and engineers under age 26. ‘Outer space’ is the most widely held explanation of their origin.

It is obviously true that even if the reality of UFOs were somehow to be fully established, it would not prove the reality of extraterrestrial visitors. UFOs could possibly be, for example, some poorly understood atmospheric phenomenon, or the result of some secret terrestrial technology, or even a life form or natural phenomenon which lies totally beyond the scope of present-day science. But in the public mind, the subject of UFOs is inextricably linked with the idea of extraterrestrial intelligent life, and since ETI is the subject matter of this book, I shall henceforth adopt the popular usage of terms, and examine UFO reports in the context of the evidence they purport to contain concerning extraterrestrial visitors.
