Extraterrestrial Life


The word 'Extraterrestrial' is used to define the developed life with more advanced technology than humanity that occurs outside of the earth and that probably did not originate from the Earth.

The Drake Equation is an attempt to encapsulate all the variables that would be relevant to establishing the number of intelligent civilizations that existed in our Milky Way Galaxy and which were broadcasting radio signals at this particular point in time. The Drake Equation is composed of seven terms.

The equation was written in 1961 by Frank Drake, not for purposes of quantifying the particular number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the Search for Extraterrestrial Intelligence (SETI) under NASA.

The science of Extraterrestrial life in all its forms is known as Exobiology or Astrobiology. It is also called Alien Life (whether, if it is a sentient and relatively complex individual, simply it's called an Extraterrestrial or Alien).

Extraterrestrial life forms, especially intelligent once, are often referred to in popular culture as Aliens or ETs. The popular belief in extraterrestrial life has been fuelled since the mid twentieth century by numerous reports of UFO sighting and claims of alien abduction. On the other hand, Christian skeptics consider them to be merely apparition of angels and demons from the spirit world.
