Carbon dating doesn t
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.
This is only because it is well calibrated with objects of known age.
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.
