The reason this age may not be a true age—even though it is commonly called an absolute age—is that it is based on several crucial assumptions.
Most radiometric dating techniques must make three assumptions: The major problem with the first assumption is that there is no way to prove that the decay rate was not different at some point in the past.
The Bible gives us a much more reliable history of the earth as it was recorded by God.
Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.
Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.
The starting isotope is called the parent and the end-product is called the daughter.
The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.
Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.
