Isotope: A version of an atom that differs from other atoms of the same element only in the number of neutrons.Chronological Analysis of the Scriptures- Literal interpretation of the scriptures led some people to conclude that the Earth was created approximately 6,000 years old.In fact, Archbishop Usher of Ireland calculated that the Earth was created at 9 AM on It was believed that prior to the Great Flood, Earths surface was flat and its climate was mild.The work of geologists is to tell the true story of Earth's history—more precisely, a story of Earth's history that is ever more true.A hundred years ago, we had little idea of the story's length—we had no good yardstick for time.
