William Shuler Harris, Life in a Thousand Worlds — Are There More Worlds Than One… (1905)
“ We cannot possibly grasp an idea of such infinite distances, neither can we form any adequate conception of the long, long stretches between star and star, which is the same as saying, between solar system and solar system. In our Milky Way the stars seem to be crushed together into a whitish jelly, but the awful truth looms up before us with all sublimity that, although these stars seem to lie one upon another, they are millions and trillions of miles apart. In regard to our own solar system much speculation is rife as to the existence of human creatures on the several larger planets. ”
