Dating earth’s history
WebAug 1, 1997 · The dating of rocks by the radioactive decay of certain minerals is undoubtedly the main argument today for the dogma of an old earth. But the Bible clearly teaches a recent creation of both the heavens and the earth, so Christians have often tried to reinterpret this doctrine to accommodate the long ages required by radioactive dating. … WebThe simplest and most intuitive way of dating geological features is to look at the relationships between them. There are a few simple rules for doing this, some of which we’ve already looked at in Chapter 6. For example, …
