There have been disagreements between factions of Bible believers about the time period that the first few verses the Bible covers and particularly how long the earth has been here. Young Earth Creationists think that the Earth is only about 6000 years old and that the first verse in Genesis demonstrates that God brought the earth into existence around 4004 BCE. The Gap Theory thinks that the Earth was created an indefinite time period ago and that the first verse could have occurred billions of years ago (mainstream scientists say 4.5 billion). The second verse takes place again around 6000 years ago around a desolate and void earth. This likely is caused by Satan's rebellion that brought one third of the angels with him against God. However, there is scriptural proof that shows a strong case for the Gap Theory by comparing the other days of creation and seeing that God's work is perfect, plus other references later in the Bible such as Deuteronomy 32:4 showing His perfection. A formless and ruined world would not fall into the pattern that God has set.
