Final answer:
The Pharaoh was primarily the earthly representation of Horus, the god connected to the sky and kingship. Different pharaohs were also associated with other gods like Amon-Re and Aten, the latter particularly during Akhenaten's monotheistic reign.
Step-by-step explanation:
The god that the Pharaoh said to represent on Earth was primarily the god Horus, depicted as a falcon, who was connected to kingship and the sky. As the human incarnation of Horus, the pharaoh was seen as the embodiment of justice and truth. Additionally, during different periods, pharaohs were associated with various deities. During the Middle Kingdom, the pharaohs introduced the worship of Amon-Re, who became the king of gods and the father of the pharaoh. However, in the Amarna Period, Pharaoh Akhenaten established a monotheistic worship of Aten, represented by the sun disk, as the supreme and only deity, in marked contrast to the traditional polytheistic Egyptian religion.
The spiritual belief system in Ancient Egypt was deeply integrated with their rulers, and the pharaoh's godly representation was part of maintaining ma'at, or cosmic order, which was essential for the prosperity of the country and the wellness of its people. The divine role was not just limited to a single patron god but was connected to the broader pantheon of Egyptian deities.
