Sanderson claims that most UFOs are actually atmospheric beasts. He theorizes that atmospheric beasts are animals that live in the clouds. Sometimes the atmospheric beast is reported to change shape, color, and texture. People who believe in atmospheric beasts think that the creature will die if they ever touch the ground. Some people even report them spitting streams of water at them. Others report that the beasts smell like mildew and feel like a giant soft tongue. They also seem to resemble animals of the sea, rather than land animals.
