UFO's or Unidentified Flying Objects refer to anything in the air which cannot be identified.
Some have logical explanations but others do not. Our planet is extremely isolated in our solar system so is it possible for other intelligent life to have visited us?
As far as our technology is concerned, it is impossible, but what about technologies far more advanced than ours? Is it possible that we are alone in the universe? The universe is a massive place, far beyond our comprehension. Maybe we are alone in this solar system but what about other solar systems?
Everything in this world is aimed to protect us. If you take it to the most basic food chain, everything exists so that something else can survive. Can this be accidental or has something or someone engineered all of this? If so, where are they now? Do they still exist?
We will try to address some of these questions from tales of people who claim to have been abducted by aliens to examining evidence given about the mysteries of the Nazca Lines.
