In popular cultures, "Extraterrestrials" are life forms — especially intelligent life forms— that are of extraterrestrial origin (often also called "aliens").
Famous quotes containing the word life:
“The true colour of life is the colour of the body, the colour of the covered red, the implicit and not explicit red of the living heart and the pulses. It is the modest colour of the unpublished blood.”
—Alice Meynell (1847–1922)
