Physics marches on.

But I still am skeptical about the use of carbon-14 ever since some creation scientists measured the carbon 14 in fossils supposed to be truly ancient and found more carbon 14 than there was supposed to be.

Evo’s responded that what they were measuring was groundwater contamination. But that just raises the question, if carbon 14 can seep into a fossil through ground water, can’t it seep out as well. How do you know how much seepage has occurred?

The reason involves the strong three-nucleon forces (a nucleon is either a neutron or a proton) within each carbon-14 nucleus. It's all about the simultaneous interactions among any three nucleons and the resulting influence on the decay of carbon-14.
