The young-earth creationist community is in the midst of an identity crisis relative to the age of the earth. Some within the community aggressively defend a strict 6,000-year-old creation and chafe even at minimal deviation on this point. For these, a rigid terminus a quo for the age of the universe is the simplest and best arbiter for establishing one’s young-earth creationist credentials. Conceding even a slightly older universe is for this group equal to (1) discarding or at the very least compromising biblical inerrancy1 and (2) granting philosophical independence to the sciences, whether astronomy, geology, biology, or archeology.2
This rigidity has not always existed in the young-earth community. John Whitcomb, patriarch of young-earth creationism and co-author of the groundbreaking work The Genesis Flood, defended a span of 3,000 to 5,000 years between the Flood and Abraham, offering a probable date for the original creation of between 6,700 B.C. and 8,700 B.C.3
