Similar to the Mayans, the Aztecs were known for their pyramids. However, there are far more Mayan ruins still in existence to this day than there are Aztec ruins.
For example, the 18th Dynasty of the Egyptians dates from the 14th Century BC, whilst the Aztecs didn't begin to flourish in the Valley of Mexico till the 14th Century AD, making any contact or communication between the two cultures impossible.
The pyramids line up -- more or less -- along this line. The ancient Egyptians aligned their pyramids and temples to the north because they believed their pharaohs became stars in the northern sky after they died. But while the Great Pyramid is aligned with the north, the other pyramids are all slightly off.
Robert Schoch notes that for centuries, starting in the period of the New Kingdom and throughout Roman times, the Great Sphinx of Giza was considered to have been built before the Pyramids. Oral traditions of villagers who live in the Giza area date the Sphinx to 5000 b.c., before Khafre's time.
Archaeologists believe that the Great Sphinx was built during Egypt's Old Kingdom (circa 2575–2150 B.C.) by the fourth-dynasty pharaoh Khafre. It is one of the world's oldest works of monumental sculpture and one of the largest.
