Where does the C-14 come from, especially in the organic materials (i.e. fossil fuels) if they are eons old?

Atmosphere (CO₂), groundwater (carbonic acid), subterranean sources. And we're talking very small, noise-level amounts here.

Let's list all the things this paper is doing wrong when it claims that its measurements are evidence for a young earth:

1. It focusses entirely upon a single measure, carbon-14, because all the other radiometric dating techniques give answers incompatible with its premise.
2. It ignores that even carbon-14 is giving answers incompatible with (too old for) its premise.
3. It ignores more mundane explanations for non-zero carbon-14 in old rocks.

They list other decay chains in the other articles on that URL.

The scientists who wrote these pieces are making a coordinated effort to present at least three decay chains (isotopes) that indicate a young earth.
