The obvious objections that secular historians have against Ussher's chronology (or any similar chronology) follow from their notion that the earth is 4.6 billion years old and not merely six thousand or so years old. That, however, is a circular argument, as the notion of a 4.6-billion-year-old Earth is based on a prior rejection of the Biblical account.
