Oraibi
Nobody built the Grand Canyon--it formed naturally because the Colorado River eroded the sides of the canyon off.
The Grand Canyon was not built, it is a natural gorge formed by the Colorado river where it runs through the US state of Arizona.
You're an idiot
About 17 million years ago. Actually the Grand Canyon was built 2 billion years ago!
It is a natural wonder.

the grand canyon
It was built to attract tourists and, thus, make money.
a Grand Canyon is nothing but a big erosion.........
The Grand Canyon was not built to be used, actually it wasn't even built at all (by human hands). Over thousands of years the Colorado River eroded the rock away into what you see now which is the Grand Canyon. Many tourists enjoy visiting it for its striking beauty and vastness.
