The Gap Theory is not consistent with the revelation given in the Bible concerning God’s work of creation. No gap of immense time occurred between Genesis 1:1 and 1:2. Genesis 1:2 describes an initial, and naturally unformed and unfilled, condition of the earth as part of God’s process of creation that took six days to complete, not the result of a primeval judgment upon an angelic civilization alleged to have existed in the ancient past. Rather, Scripture clearly teaches that the heaven and earth (i.e., the universe) and all the creatures that populate them were created in a six day period.
A detailed study of this issue, titled Gap Analysis, has been added under Creation Studies.
