Ancient Egyptian religion focuses largely on nature, beginning with the worship of animals. Animals were believed to represent the gods, who were imagined by individual tribes in early Egypt. Gradually, these sacred gods began to take human form with more distinct characteristics, but most continued to be depicted with the head of an animal.
Early Egyptians believed that Earth was a large disc. The flat center was Egypt, and the mountain areas surrounding Egypt were the rim of the disc. The heavenly skies existed above the disc, and underneath was deep water, the underworld of the Egyptians.
There are several creation myths of early Egypt. Some say that the god Ptah created the universe through thought alone, others say that the god Khnum created the disc of the world on a potter's wheel. The most popular myth, though, involved Ra appearing out of chaos and creating the cosmos through the birth of other gods.
