There is also a difference in the timescale used to explain the layers.

Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it.

Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.

Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.

The claimed “fact” that decay rates have always been constant is actually an inference based on a uniformitarian assumption.

It is true that radioisotope decay rates are stable today and are not largely affected by external conditions like change in temperature and pressure, but that does not mean that the rate has always been constant.

However, there are many methods that can be used to determine the age of the earth or other objects.

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.

If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.

Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.

Far from being data, these dates are actually interpretations of the data.

As discussed before, the assumptions influence the interpretation of the data.
