In the Babylon literature we repeatedly meet myths, legends and even the epos in which the main idea is the idea of searches of immortality, eternal life. On the contrary, in the Egyptian literature there is no poizvedeniye devoted to this subject. Egyptians did not need to look for eternal life, they "had" it.
Dead men were not mummified, they were washed, poured odorous oils, dressed more simply and buried. The dead was supplied with everything: food, clothes, jewelry, utensils. Graves were under construction of a brick. It were extensive underground chambers.
Ana met Adapa by words: "There is no mercy!", but at Tammuz and Gishzida's insistance tempered justice with mercy and decided to present to Adapa immortality. He offered it "life water" and "food of life", but that refused. :-)
