Mac Tonnies’s Cryptoterrestrial Hypothesis is a theory first expounded upon in Tonnies’s noted book by the same name. It refers to a theory that postulates that our ET visitors are not really what they appear to be, but are actually more humanoid, and more terrestrial than extraterrestrial in nature.
