You do not know if any dating technique using elemental isotopes decays at the same rates over time. You have no way of verifying that. Any claim that it is, is just a claim. There is no evidence to support this claim of yours.
Wait, are you contesting the legitimacy of radioactivity?
You do not know the amount of carbon isotopes, or carbon that was in the atmosphere long ago, or any other substance for that matter. You never will. And so you have no base line for comparison. It is all lies. Sophisticated lies, to support a needless job.
What are you talking about. Carbon? No one uses that except for relatively young organic matter.
