In popular cultures, "Extraterrestrials" are life forms — especially intelligent life forms— that are of extraterrestrial origin (often also called "aliens").
Famous quotes containing the words life and/or culture:
“Oh sure, everyone goes back to the earth at some point, but life itself is a thread that is never broken, never lost. Do you know why? Because each man makes a knot in the thread during his lifetime: it is the work he has done and that’s what gives life to life in the long stretch of time: the usefulness of man on this earth.”
—Jacques Roumain (1907–1945)
“The best hopes of any community rest upon that class of its gifted young men who are not encumbered with large possessions.... I now speak of extensive scholarship and ripe culture in science and art.... It is not large possessions, it is large expectations, or rather large hopes, that stimulate the ambition of the young.”
—Rutherford Birchard Hayes (1822–1893)
