Since the mid-20th century, active research has taken place to look for signs of extraterrestrial life, encompassing searches for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life. The writings of these thinkers show that interest in extraterrestrial life existed throughout history, but it is only recently that humans have had any means of investigating it. Descartes wrote that there was no means to prove that the stars were not inhabited by "intelligent creatures," but their existence was a matter of speculation. He theorized that all extraterrestrial bodies could be inhabited by men, plants, and animals, including the Sun. Nicholas of Cusa wrote in 1440 that the Earth was "a brilliant star" like other celestial objects visible in space, which would appear similar to the Sun from an exterior perspective due to a layer of "fiery brightness" in the outer layer of the atmosphere. William Vorilong, in the 15th century, acknowledged the possibility that Christ could have visited extraterrestrial worlds to redeem their inhabitants. Pre-modern writers typically assumed that extraterrestrial "worlds" would be inhabited by living beings. Multiple early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus Augustine references Epicurus's idea of innumerable worlds "throughout the boundless immensity of space" in The City of God. Speculation about the possibility of inhabited "worlds" outside the planet Earth dates back to antiquity. The science of extraterrestrial life in all its forms is known as astrobiology, the multidisciplinary field that investigates the deterministic conditions and contingent events with which life arises, distributes, and evolves in the universe. The Drake equation speculates about the existence of sapient life elsewhere in the universe. Such life might range from simple forms comparable to prokaryotes, to intelligent beings and even sapient beings, possibly bringing forth civilizations that might be far more advanced than humanity.
