These records provide three items of necessary information nowhere else available: (1) the names of the antediluvian patriarchs in the line of the promised Seed who would ultimately fulfill God’s Protevangelic promise (these names are accepted as authentic and repeated in I Chronicles 1:1-4 and Luke 3:36-38); (2) the chronological framework of primeval history, showing a total of 1656 years from Adam to the Flood (there is no internal evidence to suggest any gaps in these records); (3) the lifespans of the antediluvians averaged over 900 years (912 to be exact, excluding Enoch), indicating vastly superior environmental conditions then.
