Earth like planet.... yaaaaay.....
but does it really matter there is another one like this? its just as unreachable as it was before.
none of us will see it in our lifetimes, and none of us will see it for possibly hundreds of years, if we're lucky...smart....dont nuke ourselves to hell and back....lucky.
and I cant see how it would shape our view of life and the universe? maybe im just close minded on this, but I think I have to take from the hitch hikers guide to the galaxy on this one. we cant begin to comprehend our place in the vastness of the universe, and if we ever knew our heads would explode

which is exactly why we're going to build a machine that tells us our place in the universe and consequently forces out heads to explode.
but no, srsly. in the infinite vastness that none of us can even begin to imagine, there is bound to be at least one more planet that went through similar phenomena to what formed earth. there's an even infinitly smaller chance a species akin to us humans developed on it, to boot, if not nigh impossible. Gah, theres too much to say on this. "constitution of life, how other species would survive on a world we would deem uninhabitable" im gonna shut up now
