E.g., practical inter-stellar/galactic travel may be such an enormous intellectual/technological hurdle that the lifeforms that achieve it have evolved completely outside our realm of perception, or at least we cannot recognize them as intelligent life (any more than an ant recognizes us as such). I don't find that to be an altogether satisfactory solution either, primarily in that I don't think the interstellar travel problem introduces that severe of a developmental selection effect. It's also conceivable that intelligence is a broader property of the universe that is only recently emerging at technology- producing levels. This would also address the somewhat puzzling fact that our technological civilization arose essentially in the blink of an eye relative to evolutionary time scales, and yet apparently occurred at no other time in Earth's history. However, I can't say I'm entirely at ease with this idea either. In any case, I must agree that Fermi's paradox is very much an elephant in the room that doesn't get nearly the attention it would seem to merit, even in the absence of the UFO phenomenon. Or perhaps *especially* in the absence of the UFO phenomenon, in that many people seem to think that UFOs=ETs essentially resolves the paradox, which it does not, certainly not without appeal to some rather contrived scenarios.
