Expand your horizons and broaden your base of knowledge.

It's easy.

So there are two constants that are used, the ratio of carbon 12 to carbon 14 and the half life of carbon 14 which is assumed as 5730 years.

Interstingly enough, the supporter of carbon dating acknowledge the formula is not very accurate for anything that has died in the last ~60 years as the radiation from nucluear test and other types of radiation man has developed and tested has rendered the very inaccurate. So again, an assumption is drawn that modern day is the only time in history that the radiation levels have fluctuated.

All things to consider.

Then you know nothing on how oil was originated? Do you believe it was dinosaurs?

So how does this mesh with numbers that go back 3.3M and 47M years if the constants +/-3 are only for 60K years? How does that deviation propagate back?

But the second question [and I suck at this part of science, by the way], you said that the only time in history that the radiation levels have fluctuated is modern but earlier you said that you didn't understand the application of a constant math formula on a wildly dynamic atmosphere.
