When radiometric dates seem to contradict biblical events, keep in mind that these dates can be wrong. Barnes has claimed that the earth's magnetic field is decaying exponentially with a half-life of fourteen hundred years. Sedimentary rocks do not work because they are made up of a mixture of deposits of many other types of rocks, dating sites cat each of which would point to a different age. We will deal with carbon dating first and then with the other dating methods.

  1. All radiometric dating methods use this basic principle to extrapolate the age of artifacts being tested.
  2. They then use that absolute date to establish a relative age for fossils and artifacts in relation to that layer.
  3. It is possible that the ratio of daughter to parent substances for radiometric dating could differ in the different minerals.
  4. Furthermore, different techniques should consistently agree with one another.
  5. Gentry has addressed all attempts to criticize his work.
  6. Problems can occur when using these assumptions.
