The thing that troubles me most with creation science, with respect to geologic dating methods, is that I have an academic background in that area, and can see how not only the reasoning is flawed, but much misleading and in some cases out-right false claims are made. When reading the creation science article linked ("Radio-Dating in Rubble"), there are numerous problems with it. But for the time being, let's focus on one aspect of it, the claim that Mount St Helens is not a million years old.
One thing specific to all radiometric dating methods is that they all have limitations. That is why specific methods are used for specific minerals and of approximate age. This is due to the isotope(s) being measured with respect to their half-life and method of application. When sending samples to a laboratory, dating labs provide information sheets about the samples to be tested. This is so the lab can apply the proper test method to all samples.
Now, back to the article. One of the statements in the article is, "The lava dome at Mount St Helens is not a million years old!". The implication there is that Mount St Helens is thought to be a million years old by geologists. That is not only misleading, but an incorrect statement as well. The first eruption of Mount St Helens dated by geologists/volcanologists is 40,000 - 30,000 years. Also stated, "At the time of the test, it was only about 10 years old". There it is implied that the samples sent to the testing lab were only 10 years old.
So what's the problem? The rocks dated were sent to Geochron Laboratories of Cambridge, Massachusetts. The paper work provided by Geochron Laboratories they had to fill out accompanying the samples included the following statement, "We cannot analyze samples expected to be younger than 2 M.Y." Now, ask yourself, why did the AiG article imply an incorrect age of Mount St Helens and why were samples sent to a laboratory that clearly states it cannot date rocks by the K-Ar method less than 2 million years of age? Would the lab have dated the rocks if they knew that were less than 2 million years old? Of course not. So, what does that imply about those seeking to get radiometric dated ages of those rocks?
So what happens when a fossil is unearthed and we are told that it's 2 million years old based on radiometric dating? Were just supposed to take their word for it with no way of confirming that the methodology is valid. That's why I like genetics because they can tell me all day long that the divergence between humans and chimps is just over one percent but I can refer to the actual genomic comparison that clearly states its over 4 percent. This is a classic example of an argument from credulity.
Assumption 1: Conditions at Time Zero.
Assumption 2: No Contamination.
Assumption 3: Constant Decay Rate. (Radiometric Dating: Problems with the Assumptions)
Idols of the Theater are those which are due to sophistry and false learning. These idols are built up in the field of theology, philosophy, and science, and because they are defended by learned groups are accepted without question by the masses. When false philosophies have been cultivated and have attained a wide sphere of dominion in the world of the intellect they are no longer questioned. False superstructures are raised on false foundations, and in the end systems barren of merit parade their grandeur on the stage of the world. (Francis Bacon, Idols of the Mind)
Whether you work in the field or not the validity of these methods are not beyond skepticism. I reserve the right to remain unconvinced because I've seen entirely too much of this. Time and again I've seen cultivating a 'wide sphere of dominion in the world of the intellect' and it's little more then drama. Virtually no chimpanzee ancestors except for three teeth found in the Rift Valley, a place where a lot of hominid fossils were found and not one of the skulls is ever considered an ape ancestor. There is an alternative, there is room here for skepticism. I don't think it's AIG who is being disingenuous, I think we are having these underlying assumptions imposed on us and I refuse to accept it based on academic and professional credentials alone.
Have a nice day
