Sentience, like consciousness, is a concept sometimes mistakenly used to refer to the concept of intelligence and sapience, since it does not exclude forms of life that are non-sapient (or more broadly non-intelligent or non-conscious).

Hart’s argument was extended by cosmologist Frank Tipler in his 1981 paper entitled "Extraterrestrial intelligent beings do not exist". [4] The conjecture is the first of many proposed solutions to the Fermi paradox (the conflict between the lack of obvious evidence for alien life and various high probability estimates for its existence).
METI International, known simply as METI, is a non-profit research organization founded in July 2015 by Douglas Vakoch [1] that creates and transmits interstellar messages to attempt to communicate with extraterrestrial civilizations.
An extraterrestrial civilization might bring to Earth pathogens or invasive life forms that do not harm its own biosphere. [45] Alien pathogens could decimate the human population, which would have no immunity to them, or they might use terrestrial livestock or plants as hosts, causing indirect harm to humans. [45]
