One of the many speculations put forth by ufologists is the idea that UFOs can create their own “clouds” in order to sneak into an unsuspecting city or town undetected. An impressive example of one such “UFO cloud” was spotted hovering over the scenic city of Livadeia, Greece. UFO Sightings Daily posted images and a YouTube video of this cloud documented by a resident of Livadeia and they are quite unique and impressive. But are they truly evidence of an alien visitation? Our own atmosphere has the capability to produce some of the most haunting and extraordinary meteorological phenomenon, but that does not mean that they are otherworldly.
