"The Great Wall of China is visible from space"
FALSE 98% confidence
The Great Wall is only about 15-30 feet wide - far too narrow to be seen from space with the naked eye. Astronauts, including Chinese astronaut Yang Liwei, have confirmed it's not visible. This myth has been debunked by NASA. You cannot see any man-made structure from space without magnification.
