In the beginning God created the heaven and the earth. [Dake]
We cannot say how old the earth is because we do not know WHEN the beginning was. God’s creation of the heavens and the earth in the beginning could have been millions and billions of years ago.
If geologists can prove the age of the earth to be what they claim, we have no scriptural authority to disagree. They cannot contradict the Bible, for it does not reveal any time element in connection with the earth’s original creation.
This much is certain, according to Scripture, that the earth is more than 6,000 years old, and there were inhabitants on earth before the days of Adam.
The earth was cursed and flooded, as in Genesis 1: 2 because of sin BEFORE the 6 days of re-creation in Genesis 1:3-2:25.
Lucifer was already a fallen creature when he came into Adam’s Eden, having already ruled the earth, rebelled and caused the first flood [Gen. 1:2; Isa. 14:12-14; Jer. 4:23-26; Ezek. 28:11-17; Lk. 10:18; 2 Pet. 3:5-8].
