Before modern history, petroglyphs were interpreted to be depictions of unidentified flying objects (UFOs), and extraterrestrials were left on the Indian Subcontinent, Australia, Europe, and North America. Throughout the renaissance and beyond, master painters were apparently free to depict what we refer to as UFOs in religious paintings. Airborne objects in these works are particularly remarkable considering human mechanical flight had not yet been invented. These depictions, now part of the historical record, beg the questions: “Why has the presence of UFOs been denied by 20th century governments and military agencies? Why has the American government classified research and events such as the 1947 Roswell crash? Why is the entire topic stamped ‘top secret?’ Why are air force pilots finally coming forward with unidentified aerial phenomena experiences?” Explore our wealth of UFO disclosure content to learn the backstories of UFO sightings worldwide.
