The ancient Egyptians get all the credit for pyramids, but they weren't the only ones building these massive structures. Not only did pyramids appear in neighboring areas of Africa, but halfway around the world, the Maya and Aztecs, along with the Toltecs, built stepped pyramids. These pyramids of Mexico and Central America were often used as foundations for temples. This meant they usually had flat tops instead of the pointy Egyptian style. Built at different times thousands of miles from each other, the pyramids of the Old and New Worlds still have some similarites.
