Alien Intelligence
Extraterrestrial life (from the Latin words: extra and terrestris ) is defined as life that does not originate from Earth. It is often also referred to as alien life, or simply aliens (or space aliens, to differentiate from other definitions of alien or aliens). These hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans.
The development and testing of hypotheses on extraterrestrial life is known as exobiology or astrobiology; the term astrobiology, however, includes the study of life on Earth viewed in its astronomical context. Many scientists consider extraterrestrial life to be plausible, but there is no conclusive evidence for its existence. Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life, from radios used to detect possible extraterrestrial signals, to telescopes used to search for potentially habitable extrasolar planets. It has also played a major role in works of science fiction.

Famous quotes containing the words alien and/or intelligence:
“Every one of my friends had a bad day somewhere in her history she wished she could forget but couldn’t. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . “I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again.””
—Mary Kay Blakely (20th century)
“A German immersed in any civilization different from his own loses a weight equivalent in volume to the amount of intelligence he displaces.”
—José Bergamín (1895–1983)
