Through out human history there have been periods in which a society advanced and moved away from long trusted belief systems, behaviors, and moral road maps. Everything "new" was questioned and held in suspicious regard. Change only brought chaos and uncertainty. Status-quo kept things conformed to what had always been and should always be.
"Little people", "Saint", "Angels", "Spirit Guides" or "Space Brothers" - humans appear to have always had times when they sought some power outside of themselves to vindicate a certain point of view. Often that was a plea to retain the old, sacred, tried and true ways. Sometimes it was to embrace a new vision of life and adopt new values and behaviors to improve life for everyone.
The "Contactee Movement" of the late 1940's, the 1950's when they peaked, and even into the 1960's when they lingered appear to fit into that framework of being a response to the fear of technological changes brought by a world war, the atom bomb, and a new world where life moved at a hectic new pace and old ways were being shed like the skin of a snake.
Thus, motivated by fear, con artist greed and opportunity, and often simple spiritual and metaphysical beliefs, the people of Venus, Mars or "Clarion" came to call on simple Earth people to express messages of hope, of peace, and a call to repentance for evil ways and warring habits. They enlisted these people they identified as unique, the chosen ones, the messiahs of a technological age.
This quasi religious or spiritual aspect makes them unique - along with the strong presence of con artists in the mix - and suggests they are a separate phenomena from those who witness or experience other types of UFO or alien contact. One suggests other dimensions, spiritual systems and a response to changing society and the other suggests new technologies and potential non-terrestrial life forms. The motives and methods of both suggest two totally different categories of human experience.
