>Satan, or the Devil, is one of the best-known characters in the Western traditions of Judaism, Christianity, and Islam. Surprisingly, this entity was a late-comer in the ancient world. Satan, as a totally evil being, is nowhere to be found in the Jewish Bible. He evolved during the height of the Persian Achaemenid Empire (beginning c. 550 BCE) and was adopted by Jews living under Persian rule at the time. His formal name, Satan, derives from the Hebrew 'ha-Satan'. 'Ha' means 'the' and 'Satan' means 'opposer' or 'adversary'. The name described his eventual function as the opposer of God’s creation. Greek 'diabolos', English 'devil', meant 'accuser', 'slanderer', again describing his role. The concept of Satan emerged over time and in phases.
>Evil has always existed. Humans encountered natural disasters (earthquakes, floods), wars with pillage and rape, disease, plagues, and infant mortality, man-made evil such as murders and theft, and of course, death. As the ancients constructed their religious systems, the existence of evil had to be explained and rationalized. Creation myths often designated a high god or a king of the gods, who controlled everything including the other gods as well as nature. In this capacity, they were responsible for both good and evil. The term to describe this ability is omnipotence (all-powerful). In Deuteronomy 28, God declares that he controls both prosperity and suffering. Many creation myths addressed how and why evil arose.
