The amateur footage, shown on Brazilian TV station G1, shows blurry footage of a disc-shaped object hovering in the clouds for a minute or so -- before disappearing in a bright flash of light, followed by a trail of colorful bursts.
But is it an alien visitation, or merely the latest in a storied tradition of forgeries?
G1's anchors explain that two passersby saw the object as they were driving in their car, near the town of Agudos in Sao Paulo state. They hopped out of the car to shoot the video with their handheld camera.
According to the TV station, the cinematographers reported the earth shaking at about the same time the object vanishes in a blast of light, noting that other people reported the earth moving in the same general area.
