FALSE

The claim that the Great Wall of China is visible from the Moon is a widely debunked myth 3 6. NASA and astronauts have confirmed that the structure is not visible to the naked eye from the Moon or even from low Earth orbit 2 4. Physiological limitations of the human eye prevent it from seeing the wall because it is too narrow and lacks sufficient contrast with its surroundings 1 5. Despite one source claiming otherwise 8, the scientific consensus is that no human-made object is visible from such a distance 10. Historical evidence suggests this belief started as a guess nearly 300 years ago 9.
