Almost everyone believes the “Great Wall of China can seen from the moon” myth because it was reported in Trivial Pursuit once.
But it was presented as fact before Sputnik even went into space.
No, the Great Wall cannot be seen from the moon, and neither can any other object constructed by humans.
If you don’t believe it, look at pictures.
All that’s possibly visible from the moon are clouds, water, and land masses, and even the land is not always clear.
The astronauts who have walked on the surface of the moon have also confirmed that nothing human-made is visible.
