Unfortunately, the age cannot be computed directly from material that is solely from the Earth.

When experts compare the tree-ring dates with the C dates, they find that radiocarbon ages before BC are really too young—not too old as Cook maintains. I came into the room, which was half dark, and presently spotted Lord Kelvin in the audience and realized that I was in trouble at the last part of my speech dealing with the age of the Earth, where my views conflicted with his.

So those making the argument do not even have the excuse that such an consensus existed prior to the unmanned landings.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old. Uranium and thorium have long half-lives, and so persist in Earth's crust, but radioactive elements with short half-lives have generally disappeared. In order to explain old isotopic ages on a young Earth by means of accelerated decay, an increase of six to ten orders of magnitude in rates of decay would be needed depending on whether the acceleration was spread out over the entire pre-Flood period, or accomplished entirely during the Flood.

These measurements give the value for influx rate to the Earth of about 20, to 40, tons per year. Here is how carbon dating works and the assumptions it is based upon. It has not been decaying exponentially as Barnes maintains.

The author received considerable help from the ICR technical monograph on radiometric dating by Prof. Several measurements of higher precision were available from many sources by the time Morris wrote Scientific Creationism. Yet, instead of seriously attempting to rebut them with up-to-date evidence, Barnes merely quoted the old guesses of authors who wrote before the facts were known. What he ignores is the great body of archaeological and geological data showing that the strength of the magnetic field has been fluctuating up and down for thousands of years and that it has reversed polarity many times in the geological past.

The amount of fossil fuels indicates there must have been a vastly larger quantity of vegetation in existence prior to the Flood than exists today.

The majority of the 70 well-dated meteorites have ages of 4. So, despite creationist claims, C before three thousand years ago was decaying faster than it was being formed and C dating errs on the side of making objects from before BC look too youngnot too old. The scientists reviewed the assumptions and procedures used in estimating the ages of rocks and fossils.

Without such a beginning claim, the logic would be extremely bizarre.

How Carbon Dating Works

Since sunlight causes the formation of C in the atmosphere, and normal radioactive decay takes it out, there must be a point where the formation rate and the decay rate equalizes. This calculation was performed by dividing the amount of various metals in the oceans by the rate at which rivers bring the metals into the oceans.

I will be passing these truths on, thank you.
