Rubidium 87 radiometric dating

Some of the atoms eventually change from one element to another by a process called radioactive decay.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.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.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.
