GREAT WALL OF CHINA is the only human-built structure that can be seen from MOON

This is one of the greatest urban myths that astronauts can see the Great Wall of China from the  Moon. The Great Wall of China is not visible even from the International Space Station (around 200 miles) with naked eyes and certainly not from the moon (roughly 237,000 miles away). The China's first man in space, Yang Liwei, said he couldn’t see this historical landmark from space. The American Astronaut, Jay Apt, has  also been quoted as saying that "the Great Wall is almost invisible from only 180 miles (290 km) up. The former NASA astronaut Jeffrey Hoffman clims “ I have spent a lot of time looking at the Earth from space, including numerous flights over China, and I never saw the wall”. None of the Apollo astronauts reported seeing any specific human-made object from the Moon.
