Relative dating method
Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.A full discussion of the topic must therefore include the current scientific challenge to the OE concept.This implies the earth is at least 20 million years old.Astronomical cycles can also be used to measure relative age.In other words, half of the radioactive isotope in a sample would have decayed to Nitrogen-14 (N-14) in just 5,730 years.C-14 dating of carbon-bearing materials is therefore limited to roughly 50,000 years.The time required for half the original number of parent atoms to decay is called the half life.
Dating Anomalies Here we outline a few dating methods or 'clocks' that present a dating anomaly when referenced to the widely accepted OE age of 4.6 billion years. At the outset we note C-14 cannot be used to directly date the earth for the simple reason that the unstable C-14 isotope has a half-life of just 5,730 years.
The earth precesses (wobbles like a spinning top) around the sun in a series of cycles.
These cycles affect sunlight and hence long-term can form layers in rock.
And OE Christians (theistic evolutionists) see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective.
This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation.
