The Earth really unique in its ability to support life? Right now, that’s a $300 million question. When NASA’s Kepler Mission launches in 2007, we may find the answer.
Started more than a decade ago, the Kepler Mission (www.kepler.arc.nasa.gov/index.html) is the first program to search for Earth-sized planets. What’s more, it will look for planets that, based on their orbits, are capable of supporting life.

"If we find out we?re the only Earth, there can never be a Star Trek," Borucki cautioned. There simply wouldn?t be anyone to visit..B.S.!!!! That's like saying ANWR isn't worth visiting because nobody lives there.

Even if it turns out that life is abundant elsewhere, that still doesn't answer the question of whether intelligent life exists. That requires more exacting conditions than just any ol' slime mold.

Come to think of it, I've known some pretty slimy characters who (thoeretically) pass for intelligent life forms.

There simply wouldn?t be anyone to visit.. You got it! Where do they find these Carpathians? If they are in America it's only because an ancestor had at least a trace of imagination to emigrate.

I used to buy Sagan's "Billions and billions" argument...until I read
Rare Earth by Peter Ward and Donald Brownlee. They argue persuasively that life is common but
intelligent life is exceedingly rare.
It is now my belief that we are alone or nearly so. I'd place the upper limit of the number of intelligent species in the galaxy at ~10; certainly no more than ~100.
In other words, we may as well be alone.
The Fermi Paradox and corollaries indicate that interstellar travel is either essentially impossible or completely impossible; otherwise we would already have been visited or contacted by more than one pre-existing species who have conquered the problem. So either there are no intelligent E.T.s with ultra-evolved technologies, or interstellar travel is so daunting that even 10,000-year-old technological civilizations cannot accomplish it.
In any event, we appear to be "alone", which is a very sad thing.

I agree; Ward and Brownlee's book was very persuasive. I'd like to see an updated version published in the next 5 years or so.

Not that the rare-earth hypothesis doesn't have a lot of things going for it, but this really isn't one of them.

"Or, they're just very good at hiding themselves." If intelligent life is common and interstellar travel possible, then some of them would not hide themselves. Even if you posit some sort of Twilight-Zone-like "zoo" ("This solar system restricted: Do Not Feed the Autochthons"), there would be a few which chose to ignore the "rule".
If there is a single culture (equivalent to a single E.T. species for our purposes) it might enforce a "must-hide-from-people" restriction. But if there is interstellar "diversity" then this idea is bootless.
