The zoo hypothesis speculates on the assumed behavior and existence of technologically advanced extraterrestrial life and the reasons they refrain from contacting Earth. It is one of many theoretical explanations for the Fermi paradox. The hypothesis states that alien life intentionally avoids communication with Earth to allow for natural evolution and sociocultural development, and avoiding interplanetary contamination, similar to people observing animals at a zoo. The hypothesis seeks to explain the apparent absence of extraterrestrial life despite its generally accepted plausibility and hence the reasonable expectation of its existence. A variant on the zoo hypothesis suggested by the former MIT Haystack Observatory scientist John Allen Ball is the "laboratory" hypothesis, in which humanity is being subjected to experiments, with Earth serving as a giant laboratory.

A UFO religion is any religion in which the existence of extraterrestrial (ET) entities operating unidentified flying objects (UFOs) is an element of belief. Typically, adherents of such religions believe the ETs to be interested in the welfare of humanity which either already is, or eventually will become, part of a pre-existing ET civilization. Other religions predate the UFO era of the mid 20th century, but incorporate ETs into a more supernatural worldview in which the UFO occupants are more akin to angels than physical aliens, but this distinction may be blurred within the overall subculture. These religions have their roots in the tropes of early science fiction and weird fiction writings, in ufology, and in the subculture of UFO sightings and alien abduction stories. Historians have considered the Aetherius Society, founded by George King, to be the first UFO religion.

The dark forest hypothesis is the conjecture that many alien civilizations exist throughout the universe, but they are both silent and hostile, maintaining their undetectability for fear of being destroyed by another hostile and undetected civilization. In this framing, it is presumed that any space-faring civilization would view any other intelligent life as an inevitable threat, and thus destroy any nascent life that makes itself known. As a result, the electromagnetic spectrum would be relatively quiet, without evidence of any intelligent alien life, as in a "dark forest" filled with "armed hunter(s) stalking through the trees like ghosts".
