Why was the Step Pyramid built?

Pyramids are big structures which looks like a big heap or
a a hill with a square bases and four sloping sides. These sloping sides are triangular
and meet at a point at the top.  Several ancient peoples used pyramids as tombs or
temples. The Egyptians thought that a person's body had to be preserved and protected so
the soul could live forever. The pyramids could have smooth sides or stepped sides.
Stepped pyramids are pyramids with stepped sides. Also "step pyramid" is a proper name
assigned to a specific pyramid.

The first known stepped
pyramid was built in Egypt for King Zoser at Saqqarah about 2650 B.C. It was built by
Imhotep, a great architect and statesman. The tomb rises about 60 metres in six giant
steps and is called the Step Pyramid. This pyramid is still
existing.

Several ancient peoples of Central and South
America also built pyramids.  They built stepped pyramids that had flat tops.  They used
the flat tops as platforms for their temples.

The Mochica
of Peru built pyramids made of large bricks. The ancient Maya of Central America built
pyramid-shaped mounds of earth with temples on top. The Toltec of central Mexico also
built big stepped pyramids.
