In the 1950s, two sisters named Helen and Betty Mitchell claimed to have met humanoid creatures from outer space in a St. Louis, Missouri coffee shop. We Met the Space People, written in 1959, is their account of the visitation. Judging by the book cover, the aliens looked a lot like Vulcans. Manybooks.net has released a free edition of this booklet in a variety of formats.
The space people that have negative qualities about them are coming from farther space systems, although I do not wish to imply that all space craft from farther systems is evil. Many of the craft from farther systems are very good and are also trying to help Earth; however, it is only those certain evil systems that we should consider when I say those from a farther system than our own. It is these negative beings who are here for the purpose of actually taking people from Earth to indoctrinate them with their ideas, so they in turn will cause confusion and disturbances upon the planet.
