In 1947, President Harry S. Truman ordered that all matters concerning extraterrestrial entities and technology be denied in the interests of national security. This policy remains in effect today. This has caused some information in this book to be taken from tabloid articles and non-verifiable sources. An effort was made to eliminate information from articles proven to be false. Information from whistleblowers, deathbed confessions, and written documents passed down through generations was given priority. All information is given for the reader to make their own decisions. In the first part of this book, the influence the aliens had on early Sumerian and Egyptian life based on written text over 5000 years old is given. Information that the Government is trying to hide, explaining how UFO antigravity engines work, is revealed from whistleblowers who worked on the reverse engineering of a UFO craft. Excerpts from a diary from a man who interviewed the sole survivor of the Roswell crash of 1947 are verified by actual parts of the craft that scientists say could not have been made on Earth. Leading UFO stories are discussed in detail, and a list of UFO sightings from 45,000 BCE to the present day is given. UFO tours and a list of Cities where you are more likely to view a UFO are given.
