Tas Has Sth to Say About the K-Ar Date of a Rock

Creation vs. Evolution: Some CMI Classics Aren't Classic · Tas Walker 2015 vs Tas Walker 2008 · Assorted retorts from yahoo boards and elsewhere: Tas Has Sth to Say About the K-Ar Date of a Rock

10-Year-Old Rock Dated at 2 Million Years?!
Creation Ministries International, 8 Nov. 2023

Note, a date of 2 000 000 years cannot be a carbon date. Unfortunately at one point, he actually states as if the worthlessness of radiometric dating were universal for all methods. This is where I come in:

4:56 With carbon 14, you actually do know one thing of the past.

The atmosphere functions as one sample, with C14 level going up and down in response to prevalence of cosmis radiation and to decay.

This can be tested, because historically known samples (like parts of the burial of a known person) tend to have same ages for people who lived similar number of years ago, with obvious exceptions, I mean theoretically obvious, they can be non-obvious for some while.

Where so and so in England Anglo-Saxons or where they Vikings as some source claimed?

Vikings, eating lots of fish gave them old carbon, so they date a few centuries older.

Did syphilis exist in Spain or Portugal previous to Columbus or did it come from the Azteks?

From the Azteks, Portuguese skeleta with syphilis had also eaten fish, were in fact post-Columbus, but dated to pre-Columbian times.

Unlike for instance K-Ar (Potassium-Argon) or U-Th, carbon 14 has everyday applications in detecting forgeries in art (or confirming something isn't a forgery).

Take a new Rembrandt, nobody has seen it before, could be true, he was very productive, could be a forgery, you learn his style at art schools. One of the pretty basic tests to do is carbon date it. He dissolved natural pigments in oil, and that oil was from probably flax seeds harvested the last year or so, the carbon had been in the atmosphere very recently. The canvas is also if linen, same there. All the testers need to do is to avoid the pigments which are likely to contain old carbon.

This has pretendedly been exposed, in South Africa a painting was carbon dated to thousands of years old, perhaps ten thousand. It was from recent years, about a decade old. B U T ... modern art classes also (contrary to Rembrandt) use acrylic paint. Acryl in any form (including paint), is derived from petrol and therefore from old carbon going back to Noah's Flood.

So, please don't use Mount St. Helen's K-Ar to try to totally debunk carbon 14. In Journal of Creation 29(1):6–8, April 2015, you — I'm looking at you Tas Walker — did an article where you did a bit more roughly, what I then did a bit finer. I'll cite you:

"The carbon-14 (C14) method is the one most widely used for the period of time back to about 40,000 years ago, and so this calibration curve would reflect the sorts of adjustments that would need to be made to C14 ‘dates’ in order to obtain actual dates."

Well, you said it could in principle be done, I went off and did just that!

Somewhat less important, he's a bit too partial to the Masoretic text, that's what the next thing is about. He had said "only 6000 years" ...

19:52 Or a bit more than 7000 years old. LXX reading.

7222 according to the Chronology for Christmas Day in the Roman Martyrology.

In the year after Creation 5199, and after the Flood, 2957, and after the Birth of Abraham 2015, and after the Exodus 1510 ...

Here is one where he basically gives me a cue for a much simpler calibration than the one I did for carbon ....

26:40 More argon than it should be — if you mean according to the Biblical timeline, I have a date for that. The Flood. It solidifies lava quicker, so argon gets trapped.
