Some “Harmonizing” Theories - 2
nDay-age (divine-age) theory - each “day” in Genesis is a long geological age, thus interjecting millions/billions of years into the Genesis account
nPictorial (or revelational) day theory - God revealed to Moses, through visions, what God had created.  Moses then recorded each vision as a day
nGap theory (creation/ruination/re-creation theory or restitution theory) - God created a perfect world, which was consequently destroyed (perhaps because of a war Satan had with God) and then re-created and re-populated
