When you put the mummies in the ground they decompose. Usually when you put them in the pyramids they don't fall apart as much.For thousands of years, the largest structures on Earth were 
pyramids, first the Red Pyramids in the Dashur Necropolis and then the Great Pyramid of Khunfu, the only remaining Wonder of the World. Ground is soil, a mixture of sand and organic material present on the surface of the Earth.
