Shermer’s Last Law is:
“Any sufficiently advanced ETI is indistinguishable from God.”
It’s Michael Shermer’s modification of the third law of Arthur C. Clarke’s famous three laws. It was first mentioned in Shermer’s column Skeptic in the January 2002 issue of Scientific American Magazine.
Reptilian humanoids are a common motif in mythology, folklore, science fiction, ufology, and contemporary conspiracy theories. They are variously said to be beings that evolved on Earth parallel to mankind, extraterrestrials, supernatural entities, or the remains of a pre-human civilization. Depending on context they are known by many names, including Snakepeople, Reptoids, Dinosauroids, Lizardfolk, Lizardmen or Chitauri.
Pleiadeans (also spelled Pleiadian or Plejaran) is the name given to what are said to be a group of Nordic alien extraterrestrials and “multidimensional spirit beings” from the Pleiades star cluster in the constellation of Taurus, approximately 400 light years from planet Earth. Their home planet is said to be called Erra, and various descriptions of their appearance have been given by those whom claim have been in contact with them.
Nordic aliens, also called Aryan aliens, is a name given to what are said to be a group of humanoid extraterrestrials. They are so named because they are said to resemble Nordic, Scandinavian, or Aryan racial images.
A Non-organic extraterrestrial (a.k.a. NOE) is a fictional idea which refers to an alien whose bodily structure is not composed of bioorganic materials (i.e. mechanized or electronic).
As an adjective, the term “martian” is used to describe anything pertaining to the planet Mars.
Little green men are the stereotypical portrayal of extraterrestrials as little humanoid-like creatures with green skin and antennae on their heads. The term is also sometimes used to describe gremlins, mythical creatures known for causing problems in airplanes and mechanical devices. Today, these creatures are more commonly associated with an alien species called greys.
The Kelly-Hopkinsville encounter, also known as the Hopkinsville Goblins case, is a well-known and well-documented alleged Close Encounter event in the history of UFO incidents. The event occurred near the towns of Kelly and Hopkinsville, Kentucky beginning on the evening of August 21, 1955 and continuing through the next morning. UFO researcher Allan Hendry wrote “[t]his case is distinguished by its duration and also by the number of witnesses involved.”
Greys are intelligent, humanoid extraterrestrials that appear in claims of encounters with UFO-related phenomena, especially alien abduction. The study of these phenomena is considered pseudoscientific by mainstream scientists and by virtue of their close relationship with them, Greys are generally dismissed as non-existent. Some have also criticized Greys as being too excessively anthropomorphic to be a likely candidate for real extraterrestrial life forms.
Forward-contamination is the contamination of other worlds with Earth microbes. The risk of forward-contamination is twofold: that human beings may accidentally seed a previously sterile world, thus creating “extraterrestrials” that are really of terrestrial origin (and which might even make it impossible to determine whether the life later found is terrestric or local); or that an actual alien biosphere could be devastated by Earth’s bacteria.
Exotheology is the examination of theological issues as they pertain to extraterrestrial intelligence. It is concerned with either conjectures about possible theological belief structures that extraterrestrials might have, or how our own theologies will have to adapt if faced with evidence for the existence of extraterrestrial intelligence.
The Dover Demon was allegedly sighted on three separate occasions in the town of Dover, Massachusetts on April 21 and April 22, 1977. It has remained a subject of interest for cryptozoologists ever since then. Cryptozoologist Loren Coleman was the initial investigator, the first to interview the eyewitnesses within a week of the sightings, and the individual who named the creature the Dover Demon; it was disseminated by the press, and the name stuck.
