No, I don't believe it either, but scientists are claiming that this mysterious circle on a grainy sonar scan is finally evidence that Earth has been visited by aliens.
Researchers believe the fuzzy outline is a flying saucer that ended up 300ft down on the ocean floor between Sweden and Finland.
Scans taken while they were searching for a century-old wreck showed up the shape against the dirt. The ocean exploration team which found it claims that the earth around the craft has been scarred, suggesting it has tried to move around.
Lead researcher Peter Lindberg also suggested that another explanation could be that it was 'a new Stonehenge'.
Some have even suggested it resembles the Millennium Falcon from the Star Wars series, with its distinctive front forks and round shape.
Newspapers in Sweden have put the story on their front pages and asked if this is really the first sign of extra-terrestrial life.
The shape was found at the bottom of the Gulf of Bothnia during a search for a sunken wreck which contained several cases of champagne.
