anyone? and why? Life at the single cell level? Maybe. To get beyond that has taken billions of years on Earth. To get to intelligent life has also taken a bizarre sequence of events, including at least one near extinction of our ancestors. So perhaps I wouldn't go so far as to say I doubt there's life beyond Earth, but intelligent life may be so improbable as to mean that we're the only example in the Universe. Sylvia. |

... anyone? and why? Well, given the size of the universe, the number of places we've found life on earth under extreme conditions and the fact that we can already detect some precursors in clouds in space, I'd be surprised if there isn't life of some form elsewhere. But firstly, that doesn't mean we'd recognize it (though I suspect we probably would, at least eventually). Secondly, as Sylvia says, the question of if there is intelligent life, is bigger one. Given how short the presence of intelligent life has been on Earth, I think it's exceedingly rare, to the point that it's quite possible we might be it, at least in this galaxy. It's also quite likely that intelligent life just doesn't last long enough to make an impact. It might NOT provide a great enough evolutionary advantage.

And while I'm sure you've heard of it, google Fermi Paradox As for the Fermi Paradox, there are those among us who, judging from many of the post we see on the Internet, might question the existence of intelligent life on Earth. ;) |

Although the answer to that may just be that it's too damned difficult both to travel between the stars, and to make oneself noticed by other means. Maybe if we were more intelligence we'd see ways, but here's the rub - evolution gave us intelligence because it helped us survive a severe drought in Africa, not so that we could become a starfaring race. Once we'd evolved the intelligence required to cope, we stopped evolving in that direction. Any other race would likely face the same obstacle. Sylvia. |

The existence of life elsewhere in the Universe is very much an open question. The flying spaghetti monster is an invention, and its existence in the real world a matter of considerable doubt.
