Do youbelieve in aliens? Yes or No Why?
Extraterrestrial lifeis defined as life that does not originate from Earth. Possible forms of extraterrestrial life range from simple bacteria-like organisms to sapient beings far more advanced than humans. It is unknown whether any such forms of life exist or ever existed. Various claims have been made for evidence of extraterrestrial life. A less direct argument for the existence of extraterrestrial life relies on the vast size of the observable Universe. According to this argument, endorsed by scientists such as Carl Sagan and Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth and its spacecrafts. One possibility is that life has emerged independently at many places throughout the Universe. Another possibility is exogenesis, in which life would have spread between habitable planets. Suggested locations, on which life might have developed, or which might continue to host life today, include the planets Venusand Mars; moons of Jupiter, moons of Saturn, andextrasolar planets with the potential to have liquid water. Beliefs that some unidentified flying objects are of extraterrestrial origin, along with claims of alien abduction, are considered spurious by most scientists. Most UFO sightings are explained either as sightings of Earth-based aircraft or known astronomical objects, or as hoaxes.
Several theories have been proposed about the possible basis of alien life from a biochemical, evolutionary or morphological viewpoint. Alien life, such as bacteria, has been theorized by scientists such as Carl Sagan to exist in the Solar System and quite possibly throughout the Universe. No samples have been found, although there is some controversy about possible traces of life in Martian material, of which the most famous are on the Allan Hills 84001 meteorite.

The meaning of belief To establish a common ground for the general concept of belief, I hold to the common usage of the term from the American Heritage dictionary: Belief: 1. The mental act, condition, or habit of placing trust or confidence in a person or thing; faith. 2. Mental acceptance or conviction in the truth or actuality of something. Trust. 3. Something believed or accepted as true; especially, a particular tenet, or a body of tenets, accepted by a group of persons. In its simplest form, belief occurs as a mental act, a thinking process in the brain. To "believe" requires a conscious thought accepted as having some "truth" value. To communicate this thought requires spoken or written language. Not only does belief require thought but also a mental feeling of "truth" which according to neurological brain research, occurs from the limbic part of the brain. Thus, belief occurs as a thought with a truth-value feeling attached.
