When it comes to biblical authority, the question of the age of the earth is just as vital as the question of whether evolution is true or not. The chronologies in the Bible and the length of the days of the Creation Week (they were 24 hours each) show that the earth is young. Why try to reinterpret the very clear teaching of Scripture to accommodate the fallible ideas of man that say the earth is old? Such reinterpretations undermine the authority of the Word of God.
