Thus carbon dating says nothing at all about millions of years, and often lacks accuracy even with historical specimens, denying as it does the truth of the great Flood.In reality, its measured disequilibrium points to just such a world-altering event, not many years ago.The changing ratio of C-12 to C-14 indicates the length of time since the tree stopped absorbing carbon, i.e., the time of its death.Obviously, if half the C-14 decays in 5,730 years, and half more decays in another 5,730 years, by ten half-lives (57,300 years) there would be essentially no C-14 left.It is only useful for once-living things which still contain carbon, like flesh or bone or wood.Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme.

In theory, it might be useful to archaeology, but not to geology or paleontology.

A "Back to Genesis" way of thinking insists that the Flood of Noah's day would have removed a great deal of the world's carbon from the atmosphere and oceans, particularly as limestone (calcium ate) was precipitated.

Once the Flood processes ceased, C-14 began a slow build-up to equilibrium with C-12—a build-up not yet complete.

Thus the ratio of stable C-12 to unstable C-14, which is known in today's open environment, changes over time in an isolated specimen. As long as the tree lives, it absorbs carbon from the atmosphere in the form of carbon dioxide, both C-12 and C-14.

Once the tree dies, it ceases to take in new carbon, and any C-14 present begins to decay.

    Research at the universities of Alabama at Birmingham (UAB) and Texas A&M addressing the topic of socio-economic status, among other factors, showed that none of the socio-economic status variables appeared to be positively related to outmarriage within the Asian American community, and found lower-socioeconomically stable Asians sometimes utilized outmarriage to whites as a means to advance social status.
