Although many assumptions must be piled one upon another to create the theory that "flying saucers" are from another world, only a single assumption is required to indicate that such craft--if they do indeed exist--come from the planet Earth!

UFOs, flying saucers--why have they captured and held the attention of so many people? Perhaps because we'd like to believe we are not alone in the universe. Our earth and solar system are a part of one average galaxy called the Milky Way, which contains 100 billion stars similar to our own sun. Since most of these "suns" have satellites or "planets," even the most cautous scientist will admit millions of planets in our galaxy may be capable of supporting some type of life form in some stage of evolution. These life forms might be millions of years behind us in evolution or millions of years ahead of us in intelligence. Because the evolutionary changes on Earth were created by the trillions of accidents since the first building blocks of life were created, it is inconceivable to imagine this erratic chain of evolutionary events occurring in exactly the same manner--even on a duplicate Earth--anywhere in the universe and producing the same level of potential evolutionary intelligence as man's.

The two most popular worldwide theories on flying saucers can be briefly described. The first: Flying saucers are some combination of unique weather and earth-related phenomena (such as swamp gas, freak electrical discharges from the sky or pizoelectric effects within the earth's crust); the second: They are natural objects misidentified as weather balloons, helicopters or even bright stars.

The bona fide UFO advocate, of course, will quickly point out the great number of airline pilots and qualified scientists who have observed UFOs in action and described, with some degree of mechanical detail, what was often confirmed by other qualified observers miles or even hundreds of miles away. Although many "sightings" admittedly could well be natural phenomena or wishful thinking, this group also points out the 10 percent or mroe of such sightings unexplainable even wish to class very large numbers of reputable observers as "kooks."
