- Perhaps a more important issue is that if the Earth was young, we
- would not expect to find a prevalence of consistent but falsely-
- dated old rocks. In a young Earth, rocks that date old would be
- anomalies. Young Earth vs old Earth makes different predictions
- regarding the distribution of dating anomalies. Perhaps Bales
- would like to comment on such predictions?
