Suppose, just suppose for a moment, that UFOs are real. Suppose that Unidentified Flying Objects really are craft from another planet, spaceships packed with advanced technology capable of transporting alien visitors between the stars.
I imagine you're already thinking of me as a crackpot, a conspiracy theorist, a nutter who believes in Bigfoot and fairies and the Loch Ness Monster. That might be true. Or it might not. For now, I urge you to set that all aside. Let's just theorise that, for the sake of argument, that the truth really is Out There. After all, space is big and, with a near-infinite amount of time, almost anything is possible.
So, UFOs are real and, every now and then, somebody spots lights in the sky or encounters oddly-shaped beings with perfect language skills but a strangely incomplete understanding of both politics and geography, and therefore then demand to be Taken to Your Leader.
If all that were true, some questions need to be asked. First and foremost, if their technology is so advanced, why is it that we ever get to see them at all? Surely, any technology capable of interstellar travel would allow them, whoever they are, to be permanently undetectable by eye, ear or any of our five senses, or to the senses of our primitive machines.
It seems to me that there are really only two possibilities: firstly, the reported sightings are the result of the very infrequent failure of their invisibility techniques. That a very few people, and even fewer machines, ever get a glimpse of something inexplicable, and then only by accident would imply that the aliens - whoever, or whatever, they are - are around all the time and must therefore be observing us closely.
The alternative that they deliberately want to be seen which, of course, begs the question: why? Why do they want to be seen? Exploring this second hypothesis soon descends to an attempt to unscrew the inscrutable: trying to fathom the motivations of a race of beings centuries, even millennia, beyond our own level of development is unlikely to result in a provable conclusion any time soon.
The first hypothesis also begs a question or two: if we really are under such extensive surveillance, what for? What is the purpose? What do they want to find out? Perhaps even: what are they afraid of? Surely they must be afraid of something; otherwise the investment in time and energy would be pointless, if not grotesquely expensive.
I think I know why we are being watched. I think I can prove it. If you're interested, read on...
