Extraterrestrial life

Extraterrestrial Life is simply put, life that is not from Earth and is generally refered to life that is not native to the planet in question. The more commonly used term for such life is Alien. As of yet we have yet to discover Extraterrestrial Life, although it could possibly exist in several worlds in the Star System and with Trillions upon Trillions of Stars out there and the elements that are the fundamental parts of life out there being in such abundance, it is quite likely that the processes of life started somewere out there in space.

Extraterrestrial Life in Science Fiction

Like Robots and Space Travel, Extraterrestrial Life is one of the most common concepts in Science Fiction. However, often due to a lack of creativity or budget constraints on special effects departments, Alien lifeforms in Science Fiction are often highly anthropomorphic, a few good examples Chiss and most races in Star Trek and even capable of Cross breeding. Leaving aside the breeding, this is still incrediably unlikely given that we would have more in common with Daylilies genetically and said life could ahve taken thousands of other viable paths life could have followed in evolution such as creatures being radially symetric instead of bilateral Symetry.
