Even if one would suggest that 11 out of 1000 would turn up to be argon-40 and would take 1.25 billion years to process the balance of 989 (1000-11) atoms, how could the scientists account for 11 to be immediate and the balance of 989 atoms to 1.25 billion years not proportionally?(It wasn’t until 1885 that Carl Auer von Welsbach established that ‘didymium’ was actually composed of two distinct, new elements: neodymium and praseodymium.) The above extract mentions that didymium consists of neodymium and praseodymium and yet didymium was found in Samarium.We cannot know with any certainty the age of most of the geological strata that is available to man for viewing.I would still, however tentatively, tend to agree with a given, millions-of-years-old, Earth strata-age that enjoys near unanimous scientific support. Because I can't come up with a better scientific guess than they can, and it's their field, not mine.Aging anything on Earth in the hundreds of thousands of years, or in the millions or beyond, involves little more than educated conjecture. A Guess never rises above the level of being a guess, no matter how scientific, no matter how educated, no matter how much consensus it enjoys, no matter how well it "fits" any popular hypothesis.Even with full, 100% consensus in the scientific community, in the absence of any empirical evidence, conjecture still remains conjecture.The real problem in this situation lies in trying to determine if the proponents of the given strata-age are real scientists, or merely disciples of the faith of Scientism, play-acting at being real scientists.
Very old carbon such as found in coal deposits is radioactively dead and useless for carbon dating. So very old things may not be measured at all, and younger things may not be measured with precision.
Nitrogen atoms in the upper atmosphere are bombarded by neutrons produced by cosmic radiation resulting in radioactive carbon (C14) that becomes incorporated into atmospheric carbon dioxide.
While animals inhale and utilize oxygen and exhale carbon dioxide, plants inhale and utilize carbon dioxide and exhale oxygen.
So, the now C14-incorporated carbon dioxide is breathed and absorbed into all carbon dioxide breathing plants, and then the plants are eaten by animals, and the C14 passes into animal tissues.
Even carnivores that eat only animal tissue absorb C14 from that animal tissue.
