A religious cosmology (also mythological cosmology) is a way of explaining the origin, the history and the evolution of the cosmos or universe based on the religious mythology of a specific tradition. Religious cosmologies usually include an act or process of creation by a creator deity or a larger pantheon.The universe of the ancient Israelites was made up of a flat disc-shaped earth floating on water, heaven above, underworld below. Humans inhabited earth during life and the underworld after death, and the underworld was morally neutral; only in Hellenistic times (after c.330 BC) did Jews begin to adopt the Greek idea that it would be a place of punishment for misdeeds, and that the righteous would enjoy an afterlife in heaven. In this period too the older three-level cosmology was widely replaced by the Greek concept of a spherical earth suspended in space at the center of a number of concentric heavens.Around the time of Jesus or a little earlier, the Greek idea that God had actually created matter replaced the older idea that matter had always existed, but in a chaotic state. This concept, called creatio ex nihilo, is now the accepted orthodoxy of most denominations of Judaism and Christianity. Most denominations of Christianity and Judaism claim that a single, uncreated God was responsible for the creation of the cosmos.This book gives an overview of the religious cosmologies, creationism or creation myths that are associated with Buddhism, Judaism, Christianity, Jainism, Islam, Zoroastrianism and numerous others.The purpose of this series of books on religion, mythology and theology is designed to illuminate the necessity to emphasize our common humanity and eliminate the battles and divisiveness that exist within the ongoing religious struggles.This book is designed to be a general overview of the topic and provide you with the structured knowledge to familiarize yourself with the topic at the most affordable price possible.
