Rocks are made up of many individual crystals, and each crystal is usually made up of at least several different chemical elements such as iron, magnesium, silicon, etc.You cannot predict exactly when any one particular grain will get to the bottom, but you can predict from one time to the next how long the whole pile of sand takes to fall.Once all of the sand has fallen out of the top, the hourglass will no longer keep time unless it is turned over again.Many people have been led to be skeptical of dating without knowing much about it. In spite of this, differences still occur within the church.For example, most people don't realize that carbon dating is only rarely used on rocks. A disagreement over the age of the Earth is relatively minor in the whole scope of Christianity; it is more important to agree on the Rock of Ages than on the age of rocks.Radiometric dating techniques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old.

Many Christians accept this and interpret the Genesis account in less scientifically literal ways.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

However, some Christians suggest that the geologic dating techniques are unreliable, that they are wrongly interpreted, or that they are confusing at best.

Unfortunately, much of the literature available to Christians has been either inaccurate or difficult to understand, so that confusion over dating techniques continues.

Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
