Nothing in the universe is unique and alone, and therefore in other regions there must be other earths inhabited by different tribes of men and different breeds of beast. - Titus Lucretius, De Rerum Natura circa 50BCE The question, Are They Out There? is not a new one. Since ancient times, humans have wondered about the potential of alien life. Between May 1, 2023, and June 1, 2024, alone, sightings of more than seven hundred unidentified aerial phenomena were reported-and twenty-one of these cases are still under investigation. They can't be explained by common objects. In Are They Out There? retired Colonel Gene P. Abel sifts through the accounts of military professionals and eyewitnesses alike in search of the truth about extra-terrestrial visitors. Discover what Colonel Abel has uncovered, and what the government might not be telling us, in this gripping new look at the history, and potential future impact, of UFOs, and alien contact.
