→You Just Gotta Be Kidding Me: Several logical problems with Darkmind1970's post.

:::Now let me get this straight: you're only ''now'' saying that the lava that appears at an eruption should still contain a great deal of daughter nuclide? That doesn't make a bit of sense to me. I think you're misrepresenting the science here, and I demand that you produce a citation that the rest of us can check out for a comment that I consider outrageous.--[[User:TerryH|TerryH]]<sup>[[User talk:TerryH|Talk]]</sup> 19:01, 6 February 2008 (EST)

::: One of the main problems with Darkmind1970's post is that he's essentially explaining why radiometric dates can be wrong (because the rock material is older than when it was laid down), which is really a tacit admission, that you can't rely on radiometric dates, just as the creationists have been claiming for years! A second problem is that he essentially claims that you need to know how old an object is before you can use a dating method to see how old it is! Kinda defeats the purpose, I would think! Third, he fails to adequately explain ''why'' K-Ar dating cannot be used on young objects. If a few thousand years is insufficient to accumulate enough argon to detect, how come they detected it and were therefore able to supply a date? Surely his logic means that anything younger than 6,000 years would give an age of zero? But it didn't! His argument is self-defeating. If you date a sample at 2,800,000 years (which TerryH quoted above), according to Darkmind1970, it could be (a) 2,800,000 years old (i.e. the method works when used correctly), or (b) younger than 6,000 years (i.e. the method didn't work because it wasn't used correctly). So how do you decide which it is? If he is correct, then ''such dating methods cannot be used to demonstrate that items are more than 6,000 years old''! [[User:Philip J. Rayment|Philip J.
