Is this person insane? A mountain is not a sculpture and we certainly didn't "erect" the mountain.
Nobody owned that land when the settlers arrived. The indians were nomads. They’d stay in a place until they’d killed off all the game animals, and then move on. The settlers claimed a piece of land, put down roots, enclosed a spring or dug a well, built a home and barn, tilled the soil, grew crops, kept livestock. In civilized areas, improving of a parcel of land confers ownership. Wm. Penn gave settlers 50 acres. All they had to do was improve it with buildings, and work it.
