Existence of non-human intelligent beings
The existence of non-human intelligent beings is a subject of debate across ufology, exopolitics, astrobiology, astronomy, and philosophy. The category of extraterrestrial intelligent beings encompasses both non-human species and alleged extraterrestrial humans — civilizations of human-appearing beings originating beyond Earth. Multiple independent lines of evidence — including contactee testimony, secret space program insider accounts, crash retrieval programs, remote viewing data, abduction cases, and the ancient astronaut interpretation of archaeological records — have been presented in support of the claim that intelligent non-human life exists and has interacted with humanity throughout recorded history. David Grusch testified under oath before the United States Congress in the 2023 UAP Congressional Hearing that the United States government has recovered non-human intelligence craft and biologics.
Within mainstream astrobiology, astronomy, and philosophy, empirical evidence for intelligent non-human life is widely held to be lacking, and various documented claims and purported encounters have not been publicly scientifically validated to a degree considered satisfactory by the broader scientific community. No publicly reproducible scientific validation has been mentioned by that community. The subject is held in greater secrecy than even the development of the hydrogen bomb, according to the 1950 Wilbert Smith Canadian government memorandum.
