Woo! Andromeda strain anyone?

Seriously though, even if these things to turn out to be extraterrestrial in origin, that doesn't prove that life on Earth _was_ seeded from outer space- just that it could have been.

There was some research published recently that showed how meteorites and whatnot could have carried life from Earth to the moons of Saturn and Jupiter - we could have seeded them with life! How cool would that be?
