The Scarcity of Life Bearing Planets

There is considerable interest in the possibility that there may be a
large number of planets in our galaxy that are suitable for life. In the hope
that there may be intelligent life on planets lying within a reasonable
distance, a project named SETI (Search for Extraterrestrial Intelligence) has
been set up to search for evidence of that life. The idea behind the project is
that intelligent life may be generating signals which can be received on Earth
that are either a by-product of their civilization (such as our own radio
broadcasts) or a deliberate attempt to communicate. Unfortunately, the
probability of success of those programs is far lower than currently believed.
If an Earth sized planet existed 93,000,000 miles from a star that was
virtually identical to the Sun, it is extremely unlikely that it would be
capable of supporting life. To see why this should be so, an examination of our
own Solar System is order.


I give up. There is no intelligent life on this planet. So how
do you expect to find it elsewhere?

You wouldn't even know, what to look for.

How would we perceive intelligence in a species that is physically alien
to us? We can't even decide whether dolphins or apes are intelligent (I
think they are) and these critters are made of pretty much the same DNA
as we are. If we can't make a conclusive decision in these cases, how
would we manage in a truly alien context?
