The term UFO, or Unidentified Flying Object, has become synonymous with extra-terrestrial beings, and the phenomenon goes way back in human history. Long before humans took flight, first in lighter than air balloons, and then with the Wright brothers controlled and powered flight, people had reported strange and unexplained objects in the sky. Ancient civilizations and even biblical accounts like Ezekiel’s wheel have stories of UFOs coming down to earth. Some accounts talk about ‘angels’ coming from above. Were these angels actually extra-terrestrial beings? Did they come with advice on how to survive human adolescence? Did they have harmful intentions? Were they observers documenting another world and its wide variety of life? Or are all these questions merely imaginative speculations of the human mind and UFOs all have a terrestrial explanation?
Perhaps no other space-related phenomenon has created a more controversial and passionate debate then the possibility of earth being visited by alien beings. Accusations of government cover-ups, the presumed existence of dead alien bodies, and debris from crashed alien spacecraft all add to the mystery.
