This presentation covers several mysterious phenomena including the Yeti, Loch Ness Monster, UFOs, Atlantis, and crop circles. For the Yeti, DNA analysis of a hair sample found it belonged to a brown bear, suggesting sightings are misidentifications of local wildlife. Analysis of film from Loch Ness in 1934 concluded the "monster" was actually a species of eel. Studies of UFOs have been conducted by various government organizations but their existence remains undeclared. Atlantis is considered by many to just be a story, though some believe it was real. Crop circles are also discussed but no explanation is provided.
