This is nothing more than a collection of unreferenced false assertions. The reality is that dating methods are very accurate and reliable. There are error bars, like everything in science, but multiple methods can be used on multiple samples and an average can be taken to make a very accurate estimate of the ages of various rocks, strata, and fossils
what a circular reasoning this one is!
It is very easy to read how he tries to convince himself of this nonsense.
Maybe it's because English is not your first language, Q, but once again you've totally blown it. He is not saying "Dating works because dating works", but rather simply "Dating works", which is
A. not in the slightest circular, and
B. True.
Since you seem to have absolutely no science background or knowledge, why don't you try to educate yourself in dating techniques, and you will soon see that they are based on well proven chemical and physical laws that have no connection to biology or evolution, but enable us, using them, to study biological and evolutionary principles, and DATE THEM ABSOLUTELY, that's just the way the universe works. (I can see Herald's quibble now, "Well, unless you can show it happened on July 23, precisely 623,335, 789 years ago, it's not absolute so you haven't proved anything", we don't give a **** what happened in July in that year, but if we can tell what happened within the margin of error in that period, and differentiate it from what happened a few million years later, and we can, that's sufficient. Evolutionary change happens slowly).
There are MANY scientific techniques for dating, depending on the time period and the materials available. And they're not controversial and are well-proven in the field, especially in the field where lots of money is riding on the results and the people with the money gewt extremely pissed if the research is done wrong (which are the fields that farmerman earned his bones in)).
The best-known techniques involve the decay of radioactives commonly found in nature. Carbon14 wasw the first to gain wide use. C14 is radioactive, occurs in known perecentages in anything organic, and decays when that thing dies and stops taking in new carbon. It has a relatively short half life, and is generally left in too minute quantities to be measurable after about 44,000 years, which makes it useful, among other things, for dating human artifacts, which often can be cross-calibrated against things for which we know their ages from other sources, to check the accuracy of the technique. C14 dating is also now verifiable as a college chemistry/physics experiment, reproducible in any reasonably well-equipped university lab. You could even do it yourself, quahog, if you actually happened to have a decent lab to do researcdh in. You can find directions online (tho your "research" seems to focus entirely on totally disreputable conspiracy theory and wingnut sites, rather than anything hands-on). But C14 is far from the only radioactivity tehnique. Others, which Farmerman has cited, and which the science has validated, include potassium-argon breakdown, and argon-argon. thoroughly explored previously on this thread. There are a number of other proven techniques including paleomagnetic reversals and thermoluminescence (which is useful alongside its geological uses, for figuring out when human pottery was fired). And that's just scratching the surface. Farmerman does not say "Dating works because it works" which is your dumb misreading, but rather "Dating works", and has offered the science, which you somehow conveniently forget. Bad, bad Quahog.
