As noted, every ancient culture practiced some form of religion, but where religion began cannot be pinpointed with any certainty.The argument over whether Mesopotamian religion inspired that of the Egyptians has gone on for over a century now and is no closer to being resolved than when it began.In the case of Marduk, for example, his statue was carried out of his temple during the festival honoring him and through the city of Babylon so that he could appreciate its beauty while enjoying the fresh air and sunshine.
As with many cultural advancements and inventions, the 'cradle of civilization' Mesopotamia has been cited as the birthplace of religion.
When religion developed in Mesopotamia is unknown, but the first written records of religious practice date to c. Mesopotamian religious beliefs held that human beings were co-workers with the gods and labored with them and for them to hold back the forces of chaos which had been checked by the supreme deities at the beginning of time.
Order was created out of chaos by the gods and one of the most popular myths illustrating this principle told of the great god Marduk who defeated Tiamat and the forces of chaos to create the world. Brendan Nagle writes: Despite the gods' apparent victory, there was no guarantee that the forces of chaos might not recover their strength and overturn the orderly creation of the gods.
Gods and humans alike were involved in the perpetual struggle to restrain the powers of chaos, and they each had their own role to play in this dramatic battle.
The Ethiopians consider the gods flat-nosed and black; the Thracians blue-eyed and red-haired.
