The claim that China's Great Wall is the only man-made object that can be seen from the moon with the naked eye is one of our more tenaciously incorrect "facts," a bit of erroneous speculation which was spawned decades before we had the means to demonstrate it true, and which continues to have currency despite having long since been proved false. Some less specific versions of the Great Wall claim maintain it is the only man-made object that can be seen from "space," but although the term "space" is rather non-specific, it is not difficult to show the Great Wall claim to be false for any reasonable definition of the term.

To find the answer to many things, just grab google, and type wiki and then the item you're looking for.
In this case
wiki "wall of china"
"Veteran US astronaut Gene Cernan has stated: "At Earth orbit of 160 km to 320 km high, the Great Wall of China is, indeed, visible to the naked eye." Ed Lu, Expedition 7 Science Officer aboard the International Space Station, adds that, "it's less visible than a lot of other objects. And you have to know where to look."

seen from space means what exactly?
what height orbit, space shuttle like?
anyway, lots of man-made structures can be seen from space, by astronauts in low orbit i mean, not just the Great Wall of China. Many cities, many highways, the list is long
now if you mean how much can be seen by the best cameras on spy satellites, well they can see details as small as a couple feet across (and possibly less, i.e. single out human beings) so they can see pretty much any structure you'd care to name
hope this helps

It is commonly claimed so, but falsely. I have often heard a variant of this stating that it can be seen from the Moon.
Even during low earth orbit (160 miles above the surface) the wall cannot be seen.

It is debatable in regards to using the naked eye to view the Great Wall from space.

Sure, the only man-made object that can be seen from orbit.

It is only the man made object that can be seen from space.

I've read that the space shuttle astronauts can see it from space.
