Sighting of Unidentified Flying Objects (UFO) in different parts of the world have always made headlines. While some believe it to be from a different world, others completely disagree.
In one of such UFO sightings, residents of Denver spotted three glowing objects in the night sky of 4 July. Eye witnesses claim that they observed the strange orbs over the sky while watching fireworks.
The strange sighting was captured in two different video clips that was posted on You Tube and experts believe that the movement of the orbs in the second video appeared to be controlled by an alien.
