Tourists have recorded an alien and a 'floating orb' in the Mamaus region of the Brazilian rain forest, according to a video that has just appeared online.

The footage came into the possession of a noted paranormal writer, Mike Cohen, who says the region in which the video was filmed is known for its "intense UFO activity."

"This is highly compelling footage that will be hard to discredit," he asserted.

"It comes from an area known for experiencing intense UFO activity. It is rather apparent that aliens are interested in this region due to its biological diversity."

Cohen continued: "The area was also the focus of a high-level Brazilian government investigation known as Operation Prato, where the army was sent in to monitor and confirm an alien presence in the region."

The footage shows a small grey creature that appears to be arching its back. Just a few feet to the right of the suspected alien is a blue glowing "orb."

The Brazilian government tried for years to disprove the existence of Operation Prato but have since conceded that it does exist and released hundreds of files associated to it.

Operation Prato has been identified as the Brazilian government's UFO research team and many of its documents can be found on alien conspiracy website

Cohen says several Hollywood studios have approached him that want to use it in their films.
