Radiometric dating methods are completely unreliable
Most people accept the current old-earth OE age estimate of around 4. This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation. This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation. Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept.
Have you ever pulled apart a large mass of taffy and watched it break into two approximately equal masses? This is an illustration of what happens in the subatomic world when a U or U atom undergoes splitting, or fission. Nuclear fission is often used to date rocks to millions or billions of years old. But are these methods valid? There are two basic types of nuclear fission.
How accurate are Carbon-14 and other radioactive dating methods?
See also Counterexamples to an Old Earth. Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant see below for the flaws in that assumption and measuring the amount of radioactive decay that has occurred. Because radiometric dating fails to satisfy standards of testability and falsifiability , claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence. It is more accurate for shorter time periods e. Radiometric dating proceeds from the fact that certain substances radioactive isotopes decay, with near-clockwork accuracy, into other elements, and that the old elements and the new elements can be chemically distinguished and can be quantitatively measured.
You've got two decay products, lead and helium, and they're giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy.
