And we know that carbon dating in totally inaccurate. This is evidence of that.
After the discovery of the radiocarbon dating method, scientists tried to correlate their results with the dates "established" a century before. But they have not been able to do so. Of thousands of measurements, they have been able to correlate only three. These three successes were enough to make the original century old fossil/strata dating "scientific". It is on this basis that evolutionists claim that the fossiliferous strata have been dated by radioactive minerals
