The Earth might be the only place in the observable universe where there's life at all. Or the universe could be teeming with life. Finding life elsewhere - such as on Europa - would change that, particularly if it's clearly a different kind of life (nothing resembling DNA for example). As for intelligent life - our appearance on Earth was the result of a sequence of freak events, and the final push to our current level of intelligence arose from a drought in Africa that nearly wiped us out, and could easily have actually done so. So even if life turns out to be common, it could still be that intelligent life is very rare indeed. Sylvia.
