Unidentified Flying Object T-Shirt

UFO's, if your ancestors saw something flying in the sky, how would they describe the sighting. Considering that our technology has only evolved within the last few hundred years would lead you to believe that you wouldn't see any unexplained technology before that time. Yet it is believed that recorded sightings have been etched on rocks and cave walls dating back thousands of years ago. If I had an experience back then this could have been my interpretation of the sighting. The petroglyph collection of Unidentified Flying Objects and Ancient Astronauts are found in the Canyons of the Stars, Talking Canyons, New Mexico.
