2. The Face on the Surface of Mars
In 2004 when the Mars Rover sent back a bunch of photos of Mars, some people claimed to have seen some alien tools and even a model of a face: Of course, you probably see it too. The concept is called “pareidolia” and it’s the psychological phenomenon which sees people project images they’re familiar (particularly faces) with over anything that even vaguely resembles it.
Later images showed that the details of the face were just a strange coincidence made with lighting and shadows.
