Antediluvian

The antediluvian (alternatively pre-diluvian or pre-flood) period is the time period chronicled in the Bible between the fall of man and the Genesis flood narrative in biblical cosmology. The term was coined by Thomas Browne. The narrative takes up chapters 1–6 (excluding the flood narrative) of the Book of Genesis. The term found its way into early geology and science until the late Victorian era. Colloquially, the term is used to refer to any ancient and murky period. The Sumerian flood myth is alleged to be the direct mythological antecessor to the biblical flood record as well as other Near Eastern flood stories, and reflects a similar religious and cultural relevance to their religion. Much as the Abrahamic religions, ancient Sumerians divided the world between pre-flood and post-flood eras, the former being a time where the gods walked the earth with humans. After the flood, humans ceased to be immortal and the gods distanced themselves. In the Christian Bible, Hebrew Torah and Islamic Quran, the antediluvian period begins with the Fall of the first man and woman, according to Genesis and ends with the destruction of all life on the earth except those saved with Noah in the ark (Noah and his wife, his three sons and their wives). According to Bishop Ussher's 17th-century chronology, the antediluvian period lasted for 1656 years, from Creation (some say the fall of man) at 4004 BC to the Flood at 2348 BC. The elements of the narrative include some of the best-known stories in the Bible – the creation, Adam and Eve, and Cain and Abel, followed by the genealogies tracing the descendants of Cain and Seth, the third mentioned son of Adam and Eve. (These genealogies provide the framework for the biblical chronology, in the form "A lived X years and begat B".) The Bible speaks of this era as being a time of great wickedness. There were Gibborim (giants) in the earth in those days as well as Nephilim; some Bible translations identify the two as one and the same. The Gibborim were unusually powerful; Genesis calls them "mighty men which were of old, men of renown".
