Accuracy of ancient dating methods

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.

It cannot be used to date volcanic rocks, for example.

The rate of decay of N in 5,730 years (plus or minus 40 years).

However, even with such historical calibration, archaeologists do not regard C produced and therefore dating the system.

The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy.

These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.

The isotope concentrations can be measured very accurately, but isotope concentrations are not dates.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.

It makes no sense at all if man appeared at the end of billions of years.

Since the flood was accompanied by much volcanism (see Noah's Flood…, How did animals get from the Ark to isolated places? ), fossils formed in the early post-flood period would give radiocarbon ages older than they really are.
