In Gods of Aquarius , Brad Steiger proposes a radical hypothesis linking the UFO phenomenon to the spiritual evolution of humanity. Moving beyond the conventional " Extraterrestrial Hypothesis" (ETH)—which suggests UFOs are physical spacecraft from other planets—Steiger argues that UFO occupants are "Meta-terrestrials" or interdimensional beings. He posits that these entities have been interacting with humanity throughout history to guide our genetic and spiritual transformation, culminating in the current era, which he identifies as the dawning "Age of Aquarius."
