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

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

The Carbon-14 age estimating method is, at best, only useful for estimating the age of things that are thousands of years old, not millions or billions.

Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.

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.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

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

Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.

Theoretically, Creationism remains workable within a wide range of age estimates.Various radioactive elements are involved, including Carbon-14, Uranium-238, Thorium-232, and Potassium-40.By the way, it is important to understand that most rock strata “dates” were actually assigned long before the first use of radioactive age estimating methods in 1911.People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.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.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
