Because there was no written language 50,000 years ago, we do not have much information on how a "modern stone age family" lived, what they ate, where they lived, what they wore, or even what they looked like. Like Fred Flintstone, did they have leopardskin suits, go barefoot, and use a boulder for a bowling ball?

People of the Stone Age did not have the luxury of turning on the TV and watching Tim "Rock" Taylor host "Tool Time" or Bob Vilastone giving home-building tips in "This Old Cave." Nor could they dial 911 when a fire threatened them. Rather, they had to invent tools and harness the power of fire. But it was their experiments in tool-making that ultimately led to TV, cell phones, and computers.

The sands of the Nile River Valley hold many clues about one of the most mysterious, progressive, and artistic ancient civilizations. A great deal of evidence survives about how the ancient Egyptians lived, but questions remain. Even the wise sphinx would have trouble answering some of them. How were the pyramids built? Who came up with the idea for mummies and why? What was a typical day like for a pharaoh?

None of the achievements of the remarkable ancient Egyptian civilization would have been possible without the Nile River. There is always a connection between landscape and how a people develop. It does not take the wisdom of a sphinx to understand why.

Egyptian society was structured like a pyramid. At the top were the gods, such as Ra, Osiris, and Isis. Egyptians believed that the gods controlled the universe. Therefore, it was important to keep them happy. They could make the Nile overflow, cause famine, or even bring death.

Ancient Egypt, also had dynasties. They were families who often ruled for a considerable number of years and did impressive things — such as building pyramids — during their rule.

One of the Seven Wonders of the World, the pyramids defy 21st-century humans to explain their greatest secrets. How could a civilization that lacked bulldozers, forklifts, and trucks build such massive structures? Why would anyone have spent the time and energy to attempt such a task? What treasures were placed inside these monuments?

Egyptian women could have their own businesses, own and sell property, and serve as witnesses in court cases. Unlike most women in the Middle East, they were even permitted to be in the company of men. They could escape bad marriages by divorcing and remarrying. And women were entitled to one third of the property their husbands owned. The political and economic rights Egyptian women enjoyed made them the most liberated females of their time.

In the ancient Middle East, many great civilizations rose and fell. The religions of Judaism, Christianity, and Islam each trace their origins back to this part of the world. All of these civilizations arose in the area known as the Fertile Crescent. The Fertile Crescent stretches from the Mediterranean Sea in the west to the Zagros Mountains in the east. It is bordered in the north by the Taurus Mountains and in the south by the Persian Gulf and the Arabian Desert. Its shape resembles a crescent moon.

Located in what the ancient Greeks called Mesopotamia, which literally means "the land between the rivers," Sumer was a collection of city-states that occupied the southernmost portion of Mesopotamia. Most were situated along the Tigris and Euphrates Rivers, lying just north of the Persian Gulf.

The Babylonians used the innovations of the Sumerians, added to them, and built an empire that gave the world, among other things, codified laws, a tower that soared above the earth, and one of the Seven Wonders of the World.

Hammurabi is the best known and most celebrated of all Mesopotamian kings. He ruled the Babylonian Empire from 1792-50 B.C.E. Although he was concerned with keeping order in his kingdom, this was not his only reason for compiling the list of laws. When he began ruling the city-state of Babylon, he had control of no more than 50 square miles of territory. As he conquered other city-states and his empire grew, he saw the need to unify the various groups he controlled.

Much of Assyria's history is closely tied to its southern neighbor, Babylonia. The two Mesopotamian empires spoke similar languages and worshipped most of the same gods. They were often rivals on the battlefield for influence in the ancient Middle East.

Rather than destroy local economies for their own selfish gain, the Persians worked to increase trade throughout their kingdom. They standardized weights, developed official coinage, and implemented universal laws.

The Phoenicians lived along the Mediterranean coast in what is now Lebanon. They inhabited a number of different city-states, the most famous of which were Tyre, Byblos, and Sidon. These Phoenician places were often in conflict with each other for domination of the region. Because of this lack of cooperation, the Phoenicians were conquered and forced to pay tribute to the virtually every empire in the region, including the Egyptians, Hittites, Assyrians, Babylonians, Persians, and Greeks.

The Hebrew's early contribution to humankind was not wealthy empires or groundbreaking technology. Rather, it was the revolutionary idea that there was only one god, a belief known as monotheism. This one Hebrew god was called Yahweh. To the Hebrews, Yahweh was all powerful and all knowing, yet beyond human understanding. The religion based around this god influenced the founding of Christianity and Islam.

To understand the life and death of Jesus and the birth of Christianity, one must understand the context of the Roman Empire. Jesus was a Jew, as were almost all of his early followers.

A man meditating alone in a cave near Mecca received a religious vision. This vision laid the foundations for a new religion. The year was 610 and the man's name was Muhammad.

Democracy. Philosophy. Sculpture. Dramatic tragedies. The Olympic Games. Many of the fundamental elements of Western culture first arose more than 2000 years ago in ancient Greece.
