Method of dating the earth
DeYoung, Thousands … Not Billions , , 81— Alternatively, more than one dating system may be used on a sample to check the date. The following table is a sample of different element half-lives.
Every Issue. Every Year. 1845 - Present
If a scientist in any other field did this he would never be allowed to publish it. Therefore, if a scientist has strong beliefs about this topic, he or she will tend to be biased against any evidence that contradicts their beliefs with regard to the earth's reported age: Different areas had different patterns and were not able to be correlated directly.
In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.
Relative and Absolute Dating
I'll take 2 million! Geological Society, London, Special Publications. For years it was assumed that decay rates from mother to daughter element was constant. We should always start with the Bible, the ultimate source of truth. A comparison between rocks of known age Vs radiometric "age.

In reality, radioactive elements do not always decay into nonradioactive "stable" elements directly, instead, decaying into other radioactive elements that have their own half-lives and so on, until they reach a stable element. These rocks were dated at up to 3.

Each living thing should have roughly the same ratio of radioactive carbon to normal carbon Radiometric dating continues to be the predominant way scientists date geologic timescales.

The second act of the drama sees a prolonged attempt by a new generation of geologists to estimate the age of the earth from observational evidence, to come up with an answer that would satisfy the demands of newly dominant evolutionary thinking, and to reconcile this answer with the constraints imposed by thermodynamics.
