A satellite image shows a circle piece of land in Argentina in which theorists believe is the hiding place for a UFO.
According to the UFO Sighting Daily, the shape is large and circular enough to fit a 100 meter UFO through it.
Writing for the site, Scott C warned “Argentina has an overabundance of UFO sightings compared to the rest of the world and I believe this is how aliens try to hide this particular entrance to their base.”
