    none. until we discover one the answer will remain none.

    Honestly, I don't want there to be aliens.
    Think about it: say we manage to construct the Alcubierre Drive or some other method of faster-than-light transportation. If there are aliens, we would have to deal with them, but if there aren't, then the Universe is on a silver platter. We can do whatever we want, and there's no risk of interspecies war.

    I'm familiar with the Drake equation, but find it terribly inaccurate because he didn't take into account all the factors that must be in place in order for a planet to sustain intelligent life (as we know it). Scientists and astronomers are still finding things that are necessary that they didn't know in Drake's day.

    Humans on planet Dirt (Earth, Clump - whatever) not knowing of other civilizations at this point prior to the inevitable collapse of its star does not mean they do not exist.

    carbon based life forms are so amusing.

    fun to eat AND fuck.

    I personally think it would be extremely unlikely for there not to be lots of life elsewhere, but what I find most disingenuous about Drake's little calculation is the plugging in of arbitrary fractions for values that we have no way of knowing what is truly reasonable. Still, I guess it is nice demonstration.

    I'll agree with that as far as unintelligent life goes...especially single celled life or small microbes. But the chances of intelligent life as we know it is very slim, given that we've only been around for a few hundred thousand years, and all planetary bodies in the known universe are subject to fairly frequent bombardment with other space rocks (planet busters).

    That doesn't mean there hasn't been other intelligent life, or that it won't evolve again someday on another planet, but it does mean that it's very likely we're the only intelligent life CURRENTLY in the universe. And it doesn't take a genius to know that our species won't last forever. icon_wink.gif

    remember that unidentified does not mean....not of this world.

    Yes but we tend to base everything off of what it would take for life to exist as we know it. Just look at the creatures they're finding at the bottom of the deepest oceans. Animals living in temperatures hot enough to boil any other creature alive, with sulfur so thick it would kill any other animal...and yet they thrive. And that's right here on Earth!

    In infinite amount of space (as we theorize the universe is) then everything is possible. And there also is no way of telling of old or young some galaxies are and given enough time anything can happen.
