A study of Genesis 1 vs 1-2 reveals that the age of earth a shown through carbon dating is reconcilable with scripture. The exact wording of the first 2 chapters show that 'God renewed the earth'.

In Job the bible tells us that 'the angels shouted for joy' when the earth was created. This was long before Satan's rebellion. Sometime after earth was originally created, Satan rebelled, there was a war and was cast down from heaven along with his cohorts.

So we can now see that between Genesis 1 vs 1 and 1 vs 2 is a very long time that scripture never tells us how long. God created the heaven and earth in Gen 1 where the angels shouted for joy. By Gen 2, the earth became without form and void as a result of the rebellion and destruction. The earth has therefore been existing long before the 6000 years since man's appearance.
