Hey Gazrok, I agree that #s 1-3 are key to all of this, but #4 in your example zeroes right in on why it seems improbable (to me) that we would detect
nothing at all *if* the UFO activity reported around the globe in the last 50+ years were actually due to bonafide 'alien' visitors (instead of
something else pretending to be).
If 'aliens' orbit earth all the time (as some would believe), then it is reasonable that --just as NASA is in constant contact with astronauts
orbiting in a shuttle or space station-- similar communicative activity would be occurring between the near-earth and far-away 'aliens' in real
time... i.e., in the present while they are in orbit around earth.
In other words, the 'alien' signal *must* reach us/earth at the same time it reaches the 'alien'... if they are on or near earth, visiting.
Of course, assuming that 'aliens' might employ some form of transmission which we do not yet understand and/or do not have the technology to capture
is indeed one way to answer to my question... and surely is easily accepted if you give 'aliens' the upper hand.
However, given the many *visible* sightings and otherwise observed encounters that have been reported over the years, the technical ability of
'aliens' to cover their tracks and remain incognito would appear to be not quite as advanced as many assume is the case. Which seems a little
uncharacteristic of a civilization capable of traveling at warp speed and communicating telepathically (or otherwise).
Analogy: Why would ET feel it necessary to hide a phone call home, but then not think anything about hovering over human dwellings with
beacon lights on, etc.??
So, again, this discrepancy makes most 'alien' interaction with humans (at least as known & reported) seems less Trek-ish and more propagand-ish to
me... which is why I believe lack of intercepted communication pushes more towards the "aliens are not what we think
" side of the argument
than towards the "we don't know what aliens are doing
And this makes me curious: why is it that alien civilizations are assumed to be older, smarter, and more advanced than ours anyway? Is that the
truth, or is it what the 'aliens' WANT
us to believe, hmm?
Btw, nice link, FutureLibrarian.
