Answer: The Greek gods were created by man to explain the world around them, act as a means of exploration, provide legitimacy and authority to ancient Greek aristocracy, and provide entertainment for the masses. The religion of the ancient Greeks did not have a single source of written scripture such as the Bible or the Qur'an.
Greek gods are an integral part of Greek mythology. Our formal knowledge of the ancient Greek gods can be traced back to the writings of Homer in the Iliad and the Odyssey (8th century BC). In addition, many scholars believe that the myths were heavily influenced by the Mycenaean culture that existed in Greece between 1700 and 1100 BC. Remarkably, there is evidence that the beginnings of Greek mythology can be traced back to the ancient Middle Eastern cultures of Mesopotamia and Anatolia. There are many similarities between the mythology of these ancient Middle Eastern cultures and the ancient Greeks.
The Greek gods were created by man to explain the world around them, act as a means of exploration, provide legitimacy and authority to ancient Greek aristocracy, and provide entertainment for the masses. The religion of the ancient Greeks did not have a single source of written scripture such as the Bible or the Qur'an. Furthermore, the ancient Greeks did not believe in absolute truth as practiced by modern faiths such as Christianity and Judaism. Generally, a Greek city-state would devote itself to a particular god or a set of gods, and depending on the location of the city-state, the characteristics of the gods could vary widely. Many city-states erected temples to their particular gods, and these gods were honored in festivals and animal sacrifices. The ancient Greek gods normally took on human form and lived in a society similar to human society. They exhibited all the emotions of human beings and frequently intervened in human history. The most significant difference between the Greek gods and humans was that the gods were immortal and human beings were not.
It is difficult to trace the ancestry of the ancient Greek gods since there are several creation myths. A combination of the account put together by the Greek Poet Hesiod in the 8th century BC and an account written by the mythographer (compiler of myths) Apollodrous would have been recognized by most ancient Greeks. It was as follows: The god Chaos (gaping void) was the foundation of all creation. Out of this god arose Gaea (earth), Tartarus (underworld) and Eros (love). The god Eros was necessary to draw Chaos and Gaea together so that they would produce offspring. Chaos then created night and the first born of Gaea was Uranus (god of the heavens). The union of Chaos and Gaea also resulted in the creation of the mountains, seas, and gods known as Titans. The interaction of these early gods resulted in the creation of several other gods. These included well-known figures such as Aphrodite, Hades, Poseidon and Zeus. Zeus eventually waged war on his father (Cronus) and the Titans. As a result of this conflict, Zeus established a new regime on Mt. Olympus. Zeus ruled the sky, his bother Poseidon ruled the seas, and his brother Hades ruled the underworld. The creation of human beings is the result of conflicting myths. Many creation stories held that human beings sprang directly from the ground. In some cases, separate Greek societies had their own unique creation events. This is true for the Arcadians and Thebans, which both trace their beginnings to different earth-born men created in different areas. One myth states that humans were created out of earth and water, aided by the Titan, Prometheus, with his gift of fire.
