As I've argued here previously, there are certainly other
alternatives besides that they are deliberately hiding or that
they don't exist. 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.
