One of the ways to understand the age of the earth is through what is known as Flood geology. Flood geology assumes that the Flood recorded in Genesis 6-9 was universal – the entire globe was covered with water. The geological upheaval caused by the Flood would change the entire structure of the earth. Any attempt to date the earth by geological formations would be futile.


The main difficulty with Flood geology is that the majority of scientists, including those who are Bible-believers, do not find evidence of a one-year global Flood. There is also the biblical possibility that the Flood recorded in Genesis was not universal but was rather localized to one geographical area. Consequently, Flood geology should not be the determining factor in attempting to date the earth.
