That stupid, annoying buzzkill called ‘critical thought’ has ruined all our dreams of one day riding the Loch Ness monster into the sunset while high-fiving Bigfoot and using magical crystals to heal cancer.  But you’ll often hear even the most cynical skeptics admit that it’s highly likely that intelligent life exists in the universe, and it’s not entirely unlikely that they’ve visited Earth at some point.  And while UFO photo hoaxes are very common and easy to pull off, there remains some photographic evidence that continues to baffle even the experts—leaving us in child-like starry-eyed contemplation of the skies. Here are some UFO photos that might actually be legit.

Kenneth Arnold: The Original “Flying Saucer”  
 
Kenneth Arnold is widely credited with the first modern UFO sighting while flying near Mt. Rainier in 1947.  He described the craft as flying saucers, and the name stuck.  Ironically, Arnold’s depiction of the craft is much closer to a large boomerang than the classic flying saucer we associate with the term.  The above photo was taken by onlookers shortly after Arnold’s encounter, and to this day the event remains largely unexplained.
