EVER since the launch of Google Earth (more than 20 years ago now, if you can believe it), sharp-eyed internet users have been spotting neat finds.

Now it seems we may have to add a sunken ship to that list.

A Reddit user, who spotted a shadowy, ship-looking figure in a lake in Nevada, has sparked debate which has raised a number of theories.

Some of these include an underwater military base, a specialist research hub, and an ancient archaeological site.
