Why don't you tell us about it.
Please start with radiocarbon dating, as that is the one I have studied the most. I am anxious to hear your professional opinions on the "flaws."
Well, if only the earth had no climate changes and it was stagnant could a rational person take that seriously.
Radioactive dating techniques ‘prove’ that the earth is billions of years old, say evolutionists. However, these techniques are based upon several assumptions, including that rates of radioactive decay have always been CONSTANT. Now new research has shown that decay rates can VARY according to the chemical environment of the material being tested.
While the relatively small variation (1.5%) observed so far is unlikely to persuade ‘old-earthers’ to adopt a biblical time-line, the discovery that radioactive dating ‘can no longer be called precisely “clocklike”’ prompted the journal Science to comment, ‘Certainty, it seems, is on the wane.’
