Actually, the Fermi Paradox makes several unjustifiable assumptions to
arrive at the conclusion that the universe _must_ be teeming with life and
_intelligent_ life to boot. This was one of Carl Sagan's favorite topics,
and yes I'm sure it was picked apart heavily on various newsgroups.
However, there are literally thousands of reasons why said intelligent life
would never be visible to us and probably millions more which haven't even
occurred to us yet. Case in point, answer the following question, be
precise and be prepared to justify your answer:
How many intelligent species are there on Earth?

True enough, but he also unjustifiably assumes that most races figure out
his laws BEFORE being found and exterminated. I find that as equally
unlikely as the existence of said intelligent species anywhere near us in
the first place. At the risk of anthropomorphizing, I fail to see how ANY
species would arrive at such a conclusion prior to emitting at least some
betraying EM signature.
Which leaves the alternative - they are exterminated before emitting such a
signature. Since we haven't yet been eliminated ourselves, I find that
unlikely as well.
All in all, I think that the MOST likely explanation is that for whatever
reason, we are alone in our little pocket of the galaxy. I would however
like to start another thread if someone would care to pick it up. The scope
of project SETI is/was rather limited. It searched for radio waves which
although a good indicator of civilization at our level of technology, is
not necessarily what we should be looking out for.
What type of emissions would an ADVANCED civilization emit? How about
neutrinos? Gravitons? Not only are these types of emissions almost a
necessity for a spaceborne civilization, they are practically impossible to

If they do, I'm not worried, we're still here.

That is what a pre-emptive strike is all about, wipe them out BEFORE they
have the ability (much less the inclination) to wipe you out.

Granted, but this still assumes that they are practically next door. There
is no evidence of anything within fifteen or twenty light years, which
cover a lot of stars. The only other possible explanation is again back to
being so advanced that we can't even see them which loops back to we are
still here and they _must_ know about us, so I'm not worried.

I agree that the other two laws are debatable, I certainly don't believe
that either of them really apply to us. Pellegrino's point was however that
they were LOGICAL, in which he is correct. Reality however does not always

Umm, were you aware that our beloved dolphins who are supposedly so
intelligent and pacifistic are in reality aggressive and warlike? They
exhibit tribal behavior and have been known to kill other dolphin species
apparently for sport? Conceding that they are still mammals and not all
that different from us compared to extraterrestrial type aliens, I still
can't help but think that the laws of evolution as we currently understand
them are pretty much going to apply no matter what species we are talking
about. Competition for survival is probably a universal constant and the
end result is predictable.
I'm not advocating that we "hunker down" and try to hide our emissions.
Just that it would be better if we didn't automatically assume that
intelligent civilizations were automatically pacifistic.
