Unfortunately, we aren't able to reliably date artifacts beyond several thousand years.Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating.Therefore it should come as no surprise that creationists at the Institute for Creation Research (ICR) have been trying desperately to discredit this method for years.

Unfortunately the ratio of carbon-12 to carbon-14 has yet to reach a state of equilibrium in our atmosphere; there is more carbon-14 in the air today than there was thousands of years ago.As Hurley points out: Without rather special developmental work, it is not generally practicable to measure ages in excess of about twenty thousand years, because the radioactivity of the carbon becomes so slight that it is difficult to get an accurate measurement above background radiation. 108) Cosmic rays form beta radiation all the time; this is the radiation that turns N-14 to C-14 in the first place. If we extrapolate backwards in time with the proper equations, we find that the earlier the historical period, the less C-14 the atmosphere had.If we extrapolate as far back as ten thousand years ago, we find the atmosphere would not have had any C-14 in it at all.Thus, a freshly killed mussel has far less C-14 than a freshly killed something else, which is why the C-14 dating method makes freshwater mussels seem older than they really are.When dating wood there is no such problem because wood gets its carbon straight from the air, complete with a full dose of C-14.

The creationists who quote Kieth and Anderson never tell you this, however.
