Human civilization advanced and grew over a long period of time according to the geographical conditions in which he lived, and the skill he demonstrated in his manual work and intellectual production. All of this was available to the ancient Egyptians, and they established a great civilization that was the first civilization in the world. This civilization began simple, then advanced step after step, until it reached its goal of progress, and enabled them to achieve a satisfied and satisfactory life for them, and they were famous in the Pharaonic era for their strength, greatness, and excellence in every science and art, but long before reaching this prosperous era.
