Aliens | Extraterrestrials
Aliens are extraterrestrials. Extraterrestrials is the word given to entities that are not from Earth, but are from a different place in the Universe, from a different solar system or planet. Earth has been trying to get in touch with aliens for many years, and has organizations like NASA who beam out signals trying to talk to find other life. But so far, there hasn’t been much luck. Aliens have been popularized a great deal in film and television. They have been reimagined as both terrifying flesh eating monsters, like in the film Alien, or as quite cute and friendly, like in the film ET.
An alien refers to being of extraterrestrial life that does not come from planet Earth. In science fiction aliens typically come from other planets. An alien can also be considered a visitor from outer space. Aliens can range from simple forms of life to beings that belong to civilizations are more advanced than human society on Earth. The science of extraterrestrial life in all forms is known as astrobiology.
We continue to search for extraterrestrial life because it is one of the biggest questions of all humanity. It is also a way to move society forward. If we do find extraterrestrial life it will be a moment always remembered and will allow us to understand more about nature and humankind. Finding extraterrestrial life will become the equivalent of the moon landing and will inspire the next generations to go into the technology field.
The Zoo Hypothesis speculates the behavior and existence of extraterrestrial life and the reasons that they may avoid contacting Earth. This hypothesis claims that aliens are intentionally avoiding Earth and communication with humans. One of the main interpretations is that they do so to allow natural evolution, sociocultural development, avoid interplanetary contamination, and just observe Earth. Aliens might want to contact humans once society has passed a certain technological, political, or ethical standard.
