The shaky amateur 25 second-long footage of unknown origin distinctly shows disk-shaped white object appearing to hover motionless over the barren US desert.
The camera phone footage is purported to have been shot in late January 2020.

And the sighting appears to have occurred approximately 132 miles (212km) from Las Vegas, using the road sign at the video’s 14 second mark.
The dubious claims about the cloud-shaped object quickly attracted scores of people to comment on the etdatabase YouTube channel.
YouTube viewer Mountain Rain appeared convinced by the UFO claims, commenting: “You know something’s up when there isn’t a cloud in the sky but this.”
And Curtis Hill agreed, writing: “Its definitely not a “normal” looking cloud at all! Thanks for sharing.”
