The Prison Planet Theory begins with a provocative premise: that humanity did not originate on Earth, we were placed here—either intentionally, forcibly, or accidentally—by an advanced and ancient extraterrestrial civilization. br br Unlike the Zoo Hypothesis, which imagines Earth as a passive observation site, this theory casts our planet as a containment zone, a kind of interstellar penal colony where humanity is either being punished, rehabilitated, quarantined or all three at once.br br This idea draws from multiple sources—like fringe science, ancient myth, and speculative cosmology. br br Proponents argue that certain features of human biology, psychology, and behavior are inconsistent with Earth’s environment. Our vulnerability to solar radiation, our chronic physical ailments, and our social dysfunctions are interpreted not as evolutionary quirks, but as signs of environmental mismatch. br Proposing Earth is not our cradle—it’s our cage.
