The Genealogy of Adam
We might accept the precise lifespans recorded in chapter 5, or we may simply look at them as symbols of a life not yet cut short by the effects of sin. In any case, over time mankind did drift away from God. Instead of being in the presence of God as it was in the garden (3:8), and even the personal relationship that Cain maintained with God (4:6), man called on God’s name from afar (4:26). The relationship continued to deteriorate to the point where man lost all regard for God, and God determined to destroy him (6:5-6).
