There have been many apparently physical sightings and landings which produced markings on the ground and other evidence that the objects were solid machines. But if those events represent the presence of true manufactured spacecraft in our atmosphere, then the overall evidence suggests that they are following a long-range plan—a covert military-style buildup—which will culminate in hostile action. In psychic phenomena and demonology we find that seemingly solid physical objects are materialized and dematerialized or apported. There are many baffling cases of houses which appeared and disappeared mysteriously. In religious demonic possession, well documented by attending priests and doctors, the victims regurgitated impossible quantities of stones and even sharp steel needles. Apparently these foreign objects materialized in their bodies. Some victims have levitated to the ceiling and had to be forcibly tied to their beds to keep from floating away.
Ufologists have constructed elaborate theories about flying-saucer propulsion and antigravity. But we cannot exclude the possibility that these wondrous "machines" are made of the same stuff as our disappearing houses, and they don't fly—they levitate. They are merely temporary intrusions into our reality or space-time continuum, momentary manipulations of electromagnetic energy. When they "lower their frequencies" (as the contactees put it) and enter a solid state, they can leave impressions on the ground. But to enter that state, they need some atoms from our world—parts of an airplane, an auto, or blood and matter from an animal or human being. Or, in some cases, they need to drain off energy from the human percipients or from power lines and automobile engines. This may seem like a fantastic concept, but we have wasted twenty years trying to simplify all this, trying to find a more mundane explanation. The fact is, all of the evidence supports our fantastic concepts more readily than it supports the notion that we are receiving visitors from Mars or Aenstria.
But if we want to be properly cautious and objective, we find ourselves facing a double-barreled dilemma. On the one hand, all the real facts of the situation, the manifestations and physical effects of the phenomenon, seem to point to a negative, paraphysical explanation. The UFOs do not seem to exist as tangible, manufactured objects. They do not conform to the accepted natural laws of our environment. They seem to be nothing more than transmogrifications tailoring themselves to our abilities to understand. The thousands of contacts with the entities indicate that they are liars and put-on artists. The UFO manifestations seem to be, by and large, merely minor variations of the age-old demonological phenomenon. Officaldom may feel that if we ignore them long enough, they will go away altogether, taking their place with the vampire myths of the Middle Ages (Keel 1970, 280-281).
