The Concept of Heaven: For the ancient Egyptians the cosmos, the created world was regarded as a three storey structure comprising heaven, earth and the lower sky. The horizon was the most important element where the sky and earth meet and where the sun enters the Duat. The Duat was considered the realm of the gods and all the human beings who died. Moreover, the mythological concept of the cosmos shows the cycle of the sun being associated with the sky goddess Nut and the imagery of pregnancy. Therefore the Egyptians beliefs about the hereafter were strongly shaped by two myths that were centered on the sun-god Re and Osiris god of resurrection.
