Extra Terrestrial Hypothesis

The UFO ETH primarily exists, early 1950’s onwards, since for the first three to four years of the then ‘flying discs’ or ‘flying saucers’ phenomena, beginning in the late 1940’s, ‘saucers’ or ‘discs’ were thought to be terrestrial in origin – secret Soviet equipment (to the Americans); secret American equipment (to the Russians). When those thoughts started to be justifiable, the apparent conclusions were that UFOs were all in the thoughts (some kind of Cold War anxiety); misidentifications, hoaxes, illusions and so on. However that turned as similarly untenable as strong case after strong case came up and proven to be unexplainable by any kind and all appropriate terrestrial possibilities.
