A former astronaut recently went on record to allege that there is abundant evidence that we are being contacted by alien races and that these civilizations have been visiting us for a very long time. These claims also state that the alien creatures' appearance is bizarre compared to any type of traditional Western point of view, that these visitors use the technologies of consciousness, and that they use "toroids", corotating magnetic disks, for their propulsion systems. In addition, the recent discovery of 1,300 exoplanets that could sustain life has rocked the scientific world. Now more and more people, from world leaders to former astronauts, are testifying not only that UFOs exist but that aliens are here and have been monitoring the human race for centuries.
