What are aliens considered?

Answer 1

In Science Fiction, aliens are fictional organisms that did not originate on the planet earth. Sometimes the term is restricted to nonhuman intelligent species from other planets; sometimes it includes organisms that are not intelligent.

In science, an alien life form is one that is not native to the planet Earth. Science has not identified any alien life forms, but there are science-based efforts to assess what they might be like, so they can be looked for. These efforts include fields such as exobiology and projects such as SETI (Search for Extra-Terrestrial Intelligence).

In law and human politics, an alien is a human being who is not a citizen of the country making an assessment of who is an alien.

Aliens may also be of Machine intelligence or artificial life and as such not "organisms". Life as we know it and understand it is but one possibility. the term "alien" is used to describe that which is different than the norm, or from us.
a intergalactic creature that has not been prove to be true and alive there is no proof yet but someday there might be proof they exist

Answer 2

ANSWER

An alien is a form of Extraterrestial life from outer space. It is unknown if such forms of life excised or ever excised. There are many different kinds of such "alien" sightings around the world. The most common type are called "greys". Greys have a humanoid kind of body, and had more than 2,000 sightings worldwide. There have been many evidence of alien creatures in the universe but not even the top scientists have found hard proof that aliens actually excised.

A UFO (short for Unidentified Flying Object) are a kind of popular phenomenon of some kind of lights through the sky noted as a alien spacecraft. The term UFO has also been used as "flying saucer" and "flying disc". UFOs have a tremendous history, going way back to year 1088, when a scholar-goverment official wrote a vivid message in his Dream Pool Essays, when he wrote about a UFO. He recorded about his testimony of an eyewitness who stated that a flying object with opening doors would shine a blinding light from its interior (from an object shaped like a pearl) that would cast shadows from trees for ten miles in radius, and was able to take off at tremendous speeds. UFOs have had more than 40,000,000 sightings worldwide and about 30,000 each day.

Answer 3

They are considered as extraterrestrials (Pronounced : Extra - ter -est - tree -al) Which mean extrordinairy in a way. Most people imagine an alien as Green with purple suits and something to do with 3 (3 eyes , fingers, ect.) (Oh it's 3, it's a magic number!) But, WE may be the Aliens. Anyway they are considered fictional.

extraterrestrial; extra- out of; terrra- Earth, land

So an extraterrestrial is literally not of this land. We may be aliens here, but we're not extraterrestrials!

------------

They are considered to be unproven at this point; for all the tall tales that have been woven, not one came with convincing scientific evidence. Someone has to be the first form of intelligent life in the Universe, and it might well be us.
