Can you really see the Great Wall of China from space?

It just doesn't seem thick enough

According to the sources I have read, the Great Wall of China is not visible by the unaided eye looking from space. William Pogue, an astronaut stationed at Skylab in the 1970s, did see the Great Wall of China from space, but he had to use binoculars to do so.

There are two issues with attempting to see the Great Wall from space. The first is that it is not very wide. The other is that there is not a great deal of contrast between it and the land.

I attempted to see how far up I could see the Great Wall from, and the Great Wall disappears completely somewhere around zoom level 12. I cannot figure out how high the observer would be at that level, but at the same level, I can see a couple of interstate highways, several major streets, and the international airport closest to my house clearly.

Yes, you can see the Great Wall of China at very low orbits and in perfect conditions in space. So you're right in how it's pretty hard to see.

It's common to say this is the only man made object that you can see from space, but that is a myth. Highways, dams, city lights, and large buildings have all been seen from space, though "space" is a vague term. It becomes a bit hard to define the actual borders of "space."

No, it's a myth. The Great Wall of China can not be seen from space. It's narrow and irregular, and irregular things are hard to be observed from space.
The first Chinese astronaut that was lifted in to the outer space,Yang Liwei gave a clear answer to reporters after reaching the ground from space, and answer was "No".
Same answer was given by other astronauts that were in space, like Neil Armstrong and Buzz Aldrin.

Under perfect conditions small sections of the Great Wall of China have been photographed from space. Nobody has ever reported seeing it with the naked eye, though. Even if The Great Wall was visible it would be nearly impossible to differentiate from the surrounding terrain. It all looks the same from space.

Sure that you can see it.

Look at here:
