Carbon 14 not used for dating
This value of 0.2 p MC is very close to the value of 0.195 p MC found within Figure 1.
About nine half-lives would have to elapse for a starting value of 100 p MC to decrease to 0.2 p MC.
We find that about 18 such halvings are required for the p MC value to drop below 0.001 (Figures 1 and 2).
(We could “round up” the value of 0.0007 p MC at 17 half-lives to 0.001 p MC, but the 0.00038 p MC at 18 half-lives is definitely below the detection threshold.) Since each half-life is 5,730 years, this means that no C has even been detected in diamonds, which some scientists claim are billions of years old!
Virtually all fossils found within sedimentary rocks are the remains of creatures that perished during the Genesis Flood about 4,500 years ago.
Yet a skeptic might point out that the amounts of C found in these organic samples are smaller than what one might expect if they are only about 4,500 years old.
And 4,500 years is less than one radiocarbon half-life, so from Figure 2 we might expect 4,500-year-old samples to have C found within organic samples thought to date from the time of the Flood is generally only about 0.1 to 0.5 p MC.
But there is evidence that this decay occurred in accelerated “spurts,” Why the High Radiocarbon Age Estimates?
Evolutionists have long used the carbon-14, or radiocarbon, dating technique as a “hammer” to bludgeon Bible-believing Christians.
A straightforward reading of the Bible describes a 6,000-year-old universe, and because some carbon-14 (C) age estimates are multiple tens of thousands of years, many think that the radiocarbon method has soundly refuted the Bible’s historical accuracy.
In principle, this decay rate may be used to “date” the time since an organism’s death.
But the calculated dates will only be accurate if the assumptions behind the method are correct.
