Aliens

Aliens define any non-earthen species that exist. Throughout mankind's ventures into the unknown, life has taken on the forms of simple single cell organisms to full ecosystems like those found on Earth and ocean planets with fish and other aquatic life. However no sapient life forms have been discovered. Most forms of alien life are carbon-based however some basic life-forms have been discovered that are silicone-based such as those found on hostile ash or storm planets with uninhabitable atmospheric compositions.
