Mac Tonnies: Assuming that UFOs represent extraterrestrial visitors (whether humanoid aliens in spacecraft or something stranger), there's no denying the secretive way in which the phenomenon has unfolded since the dawn of the "modern" UFO era in 1947. Strident debunkers have seized on the "ufonauts'" seeming desire to remain unseen as evidence that they don't exist--and maintain that studying evidence that might suggest the contrary can only be a waste of resources. Although I think the debunking argument is steeped in anthropocentric baggage, it's a fair enough question, at least in principle: Why would aliens go to the trouble of crossing interstellar distances if they possessed no interest in revealing themselves? There are several possible answers, none of them particularly comforting. 1.) We're being observed as part of some long-term anthropological study. In this scenario, occasional run-ins with UFOs and their occupants are purely accidental. The aliens rely on a screen of plausible deniability, lurking where least expected in order to further their scientific aims and taking considerable effort to leave the human population unsuspecting. 2.) We're being prepared, however patiently, for contact at some later time. Maybe the aliens are engaged in a psychosocial campaign designed to inoculate us to the presence of "others," thus ensuring we make for interesting company when we're eventually deemed ready for open dialogue. 3.) On the other hand, perhaps we're being harvested like so many unsuspecting cattle. Much of the "abduction" literature is concerned with the alleged taking of reproductive material and the creation of human-alien "hybrid" offspring.Author David Jacobs, for one, sees a distinctly malevolent agenda afoot. In his book "The Threat," he describes what amounts to an impending takeover by aliens who've been stealthily acclimating themselves to our planet. In my opinion, Jacobs' perspective is severely limited; nevertheless, it provides an engagingly paranoid synthesis that deserves attention if only to be intelligently refuted.
