Scientific arguments against carbon dating
C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere.
When the carbon dioxide, containing C14 as well as stable C12 and C13, is taken in by plants it is no longer exposed to the intense cosmic ray bombardment in the upper atmosphere, so the carbon 14 isotope decays without being replenished.
Ham fabricates elaborate tales about Adam and Eve coexisting with vegetarian ceratosauruses in the Garden of Eden.
Radiometric dating is the method for establishing the age of objects by measuring the levels of radioisotopes in the sample. It decays to nitrogen 14 with a half life of 5730 years.
Carbon 14 is created by cosmic rays in the upper atmosphere.
Because the evidence for common ancestry is massive, creationism is a pseudoscience akin to anti-vaccine activism, astrology, climate denial and HIV/AIDS denialism.
In fact, creationism uses the same kinds of rhetorical techniques, including quoting scientists out of context, false balance, butchering simple scientific facts, conspiracy theories, logical fallacies and so on.
