Whitley Strieber in his Communion books always emphasizes that we don't know what the hell is going on with the abduction phenomenon, and encourages intense caution and avoiding jumping to conclusions at all costs. His own experiences just got weirder and weirder the more he learned.

Paraphrasing, he said something like, Imagine if we were the ones doing the contacting, and our “visitors” included a cross-section of our own world, such as traders, Jehovah’s Witnesses, Mossad, and assorted tourists all working toward their own ends. Are they trustworthy or not? The answer of course is, how the hell is anybody supposed to know?

If they exist, at the very least they have technologies and social patterns that we have no clue about, so the only sane response is to a) learn what we can, and b) be cautious as fuck.
