Setting the World Right: 
When humanity screwed up Creation, themselves, and their relationship with God, God didn't abandon Creation or people. Rather, God began the work of fixing things. He sent a flood to wash away evil and re-create the world, but sin came back. He saw humanity isolating itself from the world and becoming arrogant so he spread them over the globe to populate and care for the entirety of the earth. In God's efforts to make the world good again, He uses people.
