There were at least three "strange" UFO sightings this week in the U.S.

In St. Luis Valley, Colo. what was described as a strange object emitting a bright light was spotted over the valley - a place where alleged UFO sightings have been reported for centuries.

Resident Judy Messolin tells Examiner that the valley has been documenting potential UFOs, aliens and flying saucers since the 1700s. She adds that the recent sighting even has authorities questioning if it's a UFO.

Authorities in Rock Hill, North Carolina, on the other hand, weren't so quick to believe a man's UFO sighting this week despite his proof. 

The man's evidence included surveillance video of a "small bright ball on screen, hover for a few seconds, then fly off again," reports Charlotte Observer. He also showed police the three circular holes pressed down in the grass - presumably from a UFO landing.

Police ruled that there was "nothing criminal" about his evidence.  

Over in New Mexico former UFC fighter George St. Pierre claimed he saw a UFO when he was driving in the car with with a group of men in Albuquerque. 

"We saw a UFO all together. I don't know what it was, but it's something that we cannot explain ... it came swift towards us and right away it changed directions and it disappeared," Pierre tells Mania News.

None of the alleged UFO sightings this week were verified if they were actually UFOs, but to the witnesses of the sightings the UFOs in the U.S. this week were very real.
