Scenarios about 'alien civilization'
The concept of non-Earth-originating intelligent species that have developed technology, culture, and social structures comparable to or beyond human capabilities. Alien civilizations represent a major subject in speculative fiction and scientific discourse about extraterrestrial life, exploring how different evolutionary paths and environments might produce sentient beings. In alternate history scenarios, they often feature as first contact events, hidden influences on human development, or as parallel societies whose existence alters Earth's historical trajectory.
