II Peter 3 makes it clear that scoffers would build their anti-biblical case for an old earth based on a denial of the Kataklusmos. It's sad that some Christians blindly follow in their footsteps and refuse to rely on the Bible as the foundation for all wisdom and knowledge. You'd think the collapse of their 'mainstream' churches and cultures (such as in western Europe where their apostasy is more prevalent) would clue them in that something is wrong.
