What Are UFO's Really?
Since before the printing press was created, UFOs have been spotted, and even before that. Objects in the sky were recorded as seen by Roman Caesars, Christopher Columbus, dozens of tribes of Native Americans, etc. Since 1947 sightings in our world has increased exponentially. So, its not so much a question of ‘Are they real’ but ‘What are they really?’
