The Bible is quite clear about the origin and timeframe for the creation of Earth and the cosmos.
If Scripture is inaccurate in this, then how can it be trusted in anything else?
Both the decaying isotope and the isotope it produces (its daughter) can be compared to an isotope of the daughter’s elemental family that does not decay.
These two ratios, when plotted on a graph for many different samples from a rock suite, should hypothetically produce a straight line under certain assumed conditions.
The appeal of isochron dating is that it does not presuppose the initial amount of the daughter nuclide in the decay sequence.
Indeed, the initial amount is not important because it can be found through this type of dating.
Potassium-Argon When you look at actual isochron plots such as the ones at the above source, there seems to be room for subjectivity.
Like Nimrod of ancient times, they know they must provide an alternative (i.e., naturalism, specifically —the belief that science alone can render truth about our world and reality) to biblical truth if they are to hold sway over the public in what is essentially a couched rebellion against God.The slope of the line is related to the age of the samples.The simplest way to think of it is this: Some rock materials (isotopes) decay, and we can determine the age of a rock in today’s laboratories by determining how much of a specific isotope contained in the rock has decayed. Reconstruction of an isochron from original data obtained from the Peat Deposits From the Site Fili Park. This isochron of the Fili Park Peat deposits indicates an age of 89,000 years. In addition the data points were the five out of ten samples that, "were interpreted to be in the more or less closed-system." However it was concluded that this isochron was the result of contamination as an open system based on the fact that the date was about 50% of the age suggested by the spore and pollen fossils in the deposit.If there is a gain or loss of daughter isotope the point moves vertically.A gain moves the point up and a loss moves the point down. A shift from contamination can take place in all of the data points, but such contamination does not affect all data points equally, so it can cause the data points to shift off the true isochron completely. Isochron dating began when scientists recognized difficulties with the assumptions of radiometric dating, especially how much of the daughter products might have been present when the mineral first formed.Isochron dating has been developed in an attempt to solve such problems.One of the indirect evidences that evolutionists universally appeal to is radioactive dating because it appears to supply the deep time their evolutionary models demand.But how accurate is their model, and how scientific is their approach? An isochron is a line on an isotope ratio diagram denoting rock samples.
