Real Aliens and UFOs Encounters Books

Do aliens exist? Hundreds of pictures and videos of UFOs are taken every year and enthusiasts believe many of them could be proof or even a hidden conspiracy. While some have been debunked as fake, there are still dozens that have left even the experts scratching their heads and wondering if we really have been visited by creatures from another planet.

Unexplained aerial observations have been reported throughout history. Many of the best known alien claims come from Project Blue Book, the name for the US government program tasked with investigating reports of UFOs from 1948 to 1969.
