why the importance of finding life on other planets?
—
maybe just a desire to prove that we are not alone ,, that in this huge void we call the cosmos, that we aren’t really that special. or are we? ;-)
Until we find intelligent life (other than US, if we count), finding micro organisms or even multicellular forms will only hint that life is something natural to the universe rather than a special event sequestered on Earth. That is no small revelation, but not culture blowing.
