Finally, in the longest chapter of the book, Morris addresses "problems in biblical geology," which include commonly used dating methods (such as carbon-14 measurements) as well as geological formations, such as coral reefs, petrified forests, and varves, all of which imply great age for the earth.
Akhirnya, dalam bab terpanjang di buku ini, Morris membahas "masalah-masalah dalam geologi alkitabiah," yang meliputi metode penentuan waktu paling umum (seperti pengukuran Karbon-14) serta formasi geologi, misalnya taman karang laut (coral reefs), hutan-hutan yang membatu (petrified forests), dan varva (varves), semua sepertinya menunjuk kepada usia bumi yang tua.
