"I have never really got used to being on earth. Sometimes I think our presence here is due to a cosmic blunder, that we were meant for another planet altogether, with other arrangements, and other laws, and other, grimmer skies. I try to imagine it, our true place, off on the far side of the galaxy, whirling and whirling. And the ones who were meant for here, are they out there, baffled and homesick, like us? No, they would have become extinct long ago. How could they survive, these gentle earthlings, in a world that was made to contain us?"
- John Banville, The Book of Evidence
That quote reminds me of this one from Thomas Hardy's Tess of the d'Urbervilles:
"Did you say the stars were worlds, Tess?"
"All like ours?"
"I don't know; but I think so. They sometimes seem to be like the apples on our stubbard-tree. Most of them splendid and sound--a few blighted."
"Which do we live on--a splendid one or a blighted one?"
"A blighted one."
