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.
For example, isotopes with very long half lives are no good for dating rocks younger than about 100 million years.
This is because, in just 100,000,000 years of time, not enough parent will have decayed for daughter concentrations to be reliably measured.
When this happens in a mineral, the two departing nuclei leave behind a trail of destruction in the crystal lattice. Fission track dating is ideal for samples from recent times back to 100,000,000 years.
Beyond 100,000,000 years, the density of the tracks becomes so great (saturated) that they cannot be counted reliably.
For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.
