Assumptions about radiometric dating

In addition to the above methods of dealing with this challenge, creationists have contended a whole raft of problems with both the older and newer methods of radiometric dating.

In the special case in which parent and daughter atoms are present in equal quantities, the age of the specimen is the half-life of the parent isotope: The first assumption, that the amount of the daughter isotope in the original rock is known, is the weakest assumption.This is not an example of malfeasance, but rather the result of assuming that the theory of evolution has been proved reliable, and therefore these seeming anomalies are due to contamination or other causes of analytical error.These out of place fossils or rocks are not considered a reason to question the theory.For example, K-Ar dating assumes that there was no argon in the original rock.But if there was argon in the rock when it originally formed, then the age calculated will be millions of years too high. The greater the amount of daughter isotope, the greater the apparent age.
