Subject: Dating methods--are they reliable?

Note that the series from Samarium through Lutetium have half-lives greater than the age of the universe, 13-14 billion years. In the Uranium-Lead the half-life is approximately the age of the Earth. The half-lives are determined by counting decay events in a sample of the parent isotope. Thus, the half-lives are known to very high degree of accuracy and certainty.
Science is not just a matter of putting a sample into a machine and reading out the numbers. From past mistakes, scientists know they have to think about what they are doing. They have to take into consideration where the sample was collected and the surrounding formations and the type of crystals. By using the isochronal method of dating the process becomes self checking.
I obtained the information in the above report from:
Wiens, Roger C., Ph.D. "Radiometric Dating: A Christian Perspective"
http://www.asa3.org/ASA/resources/Wiens.html 8/18/03
A more complete discussion of radiometric dating can be found there.
Nevertheless, what I am submitting for discussion is not the method of radiometric dating, which AiG (Answers in Genesis) claims is flawed.
The question I would like to discuss is: Why, since the information falsifying their article is so readily available on the internet in a simple search on "radiometric dating", the AiG published an article based on falsehood.
1. Are they stupid? They can apparently read and write, and maintain a website and support themselves financially.
2. Are they ignorant? If so, then why didn't they inform themselves before publishing incorrect data? (Which brings us back to question 1.)
3. Are they too lazy to do a fifteen minute web search?
4. Do they know their target audience is stupid, ignorant and/or lazy, and will parrot any erroneous claim without question or verification?
5. Or are they neither stupid nor ignorant but know they can make a good living off the income generated from their ignorant, stupid and lazy disciples.
6. If anyone can think of some other reason, feel free to reply.

There is some smoke and mirrors here. Here are some of the decay series that are used in radiometric dating:Q: Almost daily we read something in a newspaper or on television, where we're told that scientists have dated something to be millions or billions of years old. Can these dating methods really be trusted?
A: First of all most dating methods do not show that rocks are millions or billions of years old. You see, there are many ways scientists can try to age-date things. Actually, most dating methods that scientists use give results far younger than evolutionists need.
Code:
[b]Isotope Product Half-Life S.N.[/b]
Samarium-147 Neodymium-143 106 billion 1.06E+11
Rubidium-87 Strontium-87 48.8 billion 4.88E+10
Rhenium-187 Osmium-187 42 billion 4.20E+10
Lutetium-176 Hafnium-176 38 billion 3.80E+10
Thorium-232 Lead-208 14 billion 1.40E+10
Uranium-238 Lead-206 4.5 billion 4.50E+09
Potassium-40 Argon-40 1.26 billion 1.26E+09
Uranium-235 Lead-207 0.7 billion 7.00E+08
Beryllium-10 Boron-10 52 million 1.52E+07
Chlorine-36 Argon-36 300000 3.00E+05
Uranium-234 Thorium-230 248000 2.48E+05
Thorium-230 Radium-226 75400 7.54E+04
Carbon-14 Nitrogen-14 5715 5.715E+3
This may or may not be necessary, but in many cases this is easily determined. Crystals are used in some dating techniques. For instance, Potassium often occurs in nature in the form of crystals of Potassium compounds. Thus we can know what percentage of the crystal started out as Potassium. . Argon is one of the "noble" gasses and so does not combine chemically with other elements to form crystals. Since the Argon escapes during the molten phase before crystals are formed it is hypothesized that any Argon found in the crystal must have formed by the decay of Potassium-40. A mass spectrometer can sort and count the occurrences of all isotopes of Potassium as well as the occurrences Argon.All dating methods involve something that changes over time. For instance, radioactive Uranium, over time, changes into a form of lead. Therefore, if scientists assume
1) they know how much was there at the beginning;
Short of a chain reaction, impossible in crystals containing the low concentrations of Potassium-40 found in nature, there is no known mechanism for changing the decay rate. Nor are there usually found in nature any naturally occurring chain reactions, although I have read about at least one, the exception that proves the rule. As far as I know, no one has put forth any hypothetical method other than a chain reaction to change any decay rate.2) this rate of change has not been disrupted through time;
There are methods of ruling out contamination. In fact in one case some "creation scientist", whose name escapes me at the moment, once tried to show that granite cooled much faster than was scientifically recognized by pointing to Polonium "haloes" in biotite mica. It was later found that the granite containing this mica was collected from a formation that that had been contaminated by ground water seeping through nearby Uranium ore which contained Polonium. Since biotite is laminate, with each crystal made of easily separate sheets of biotite, the "creation scientist's" findings were explained without recourse to correcting the theory of how long granite takes to cool.3) there's been no contamination, they can calculate how long this has been happening.
Science is not just a matter of putting a sample into a machine and reading out the numbers. From past mistakes, scientists know they have to think about what they are doing. They have to take into consideration where the sample was collected and the surrounding formations and the type of crystals. By using the isochronal method of dating the process becomes self checking.
No, AiG asserts they have been shown to be invalid. But the facts and reasoning put forth by AiG are faulty.This is how they get millions of years. But all of these assumptions have been shown to be invalid.
One cannot make a falsified hypothesis true by relying on other falsified hypotheses. Both the claim about the salinity of the oceans and Helium in the atmosphere have been falsified, and if anyone disputes this, I will be glad to address this on another thread.Not only this, but other dating methods--such as the amount of salt transported into the oceans, or the amount of helium built up in the atmosphere--indicate that the earth can't be billions or millions of years old.
I note with amusement and disgust, that only the nearly exhaustive method of radiometric dating, is claimed to be falsified, why the very problematic method of dating by the salinity of the oceans and the thoroughly falsified claims about atmospheric Helium are trotted in as "evidence" for a young earth.All dating methods are fallible, but God's Word, beginning with Genesis, is infallible.
