Researchers can find out how long ago something died using radiocarbon dating.

Bones and teeth from animals and humans, as well as artefacts made out of wood, fabric or paper are just some of the objects that can be aged using this process.

Try, for example, wearing a watch that is not waterproof while swimming. A few verified examples of incorrect radiometric ages are simply insufficient to prove that radiometric dating is invalid.

It will probably fail, but what would a reasonable person conclude from that? All they indicate is that the methods are not infallible.

If the earth were only 6000–10 000 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far.

Where are the data and age calculations that result in a consistent set of ages for all rocks on earth, as well as those from the moon and the meteorites, no greater than 10 000 years? Second, it is an approach doomed to failure at the outset.

Living organisms contain the same ratio of carbon-14 to carbon-12 as the atmosphere.

This meant that animals and plants living in the 1950s and 1960s contained much higher amounts.In order to accomplish their goal of discrediting radiometric dating, however, creationists are faced with the daunting task of showing that a preponderance of radiometric ages are wrong — that the methods are untrustworthy most of the time.Not only that, they have to show the flaws in those dating studies that provide independent corroborative evidence that radiometric methods work.Those of us who have developed and used dating techniques to solve scientific problems are well aware that the systems are not perfect; we ourselves have provided numerous examples of instances in which the techniques fail.We often test them under controlled conditions to learn when and why they fail so we will not use them incorrectly. For example, after extensive testing over many years, it was concluded that uranium-helium dating is highly unreliable because the small helium atom diffuses easily out of minerals over geologic time.Creationists seem to think that a few examples of incorrect radiometric ages invalidate all of the results of radiometric dating, but such a conclusion is illogical.
