Good observation.
I'm not playing your radiometric games.
It's over my head, and you'll kill me with experience.
Then why in god's name would you start this thread? If you have no interest in understanding the subject, why start the thread?
Let's make it clear here. Radiometric dating as currently applied to rocks measures the time since the rock solidified, as this is essentially when a "snapshot" of the radioactive elements therein solidified and could not be mixed back in. We have no way of measuring it beforehand, at least not with radiometric dating.
An analogy to carbon dating is apt here: in living organisms, there is a carbon exchange going on that constantly replenishes the relative amounts of C14 and C12 within the organism. When the organism dies, this exchange stops, and the C14 starts to decay into C12. If the organism, hypothetically, lives for thousands of years, radiocarbon dating can get you a rough date of death, but it cannot give you a date of birth, because it has no way of measuring that, because before it died, it kept a more-or-less constant rate of C12 and C14 (with some noteworthy exceptions which Kent Hovind likes to lie about). It was only after it died that the C14 started to decay without being replaced.
Similarly, argon-argon and argon-potassium dating methods rely on isotopes which, before the rock solidifies, can be replenished from the surrounding magma. However, once it solidifies, we have our "snapshot", the isotopes stop being mixed and replenished, and start to decay. This doesn't really give us any way of knowing how old the lava was, but it does give us a way of knowing when the rocks solidified. Make any sense?

If that bothers you, or you feel sorry for me, or whatever, I have this to say:
Welcome to the world of faith.
Learning how it operates can save you some needless negative emotions.
What a bizarre answer. You seem to understand that you don't get it - that you know very little about radiocarbon dating. Furthermore, you seem to understand that someone else who is trying to help you understand it
does get it. And yet you respond by essentially saying "this is how faith works", which I agree with by the way, but you say this as if it was a good thing. See, I don't understand this. It seems to me like you're using your faith to avoid an understanding of reality. That's... disappointing. I mean, if I used this argument when talking about running a red light with the grille of the mac truck that ran my ass over, I somehow feel like it would lose a bit of its poignancy.
"I realize that I don't understand this whole 'stop on red' thing, but I have faith that the light was actually green."
"HONK HONK."
"Also, apparently my bones are sticking out. Not sure that's a good thing, but I have faith that my femur is supposed to jut out of my skin in two different directions."
