If they are right, this means all C-14 ages greater than two or three thousand years need to be lowered drastically and that the earth can be no older than ten thousand years. Answer: Yes, Cook is right that C-14 is forming today faster than it's decaying.However, the amount of C-14 has not been rising steadily as Cook maintains; instead, it has fluctuated up and down over the past ten thousand years. From radiocarbon dates taken from bristlecone pines.

All living things absorb C14 carbon while they are alive on earth.

When they die, they stop absorbing C14 and it begins to decay.

And say that every 5,568 years you add another gallon of water to the mixture.

Doing that basically cuts the concentration of blue dye in half.

There are two ways of dating wood from bristlecone pines: one can count rings or one can radiocarbon-date the wood.

Since the tree ring counts have reliably dated some specimens of wood all the way back to 6200 BC, one can check out the C-14 dates against the tree-ring-count dates.

Radiocarbon dating measures the amount of carbon-14 left in human or plant remains, and then scientists can estimate the amount of time the thing has been dead Radiocarbon Dating All organic matter contains carbon, which is an element.

But there are different types of carbon, called isotopes.

Scientists can measure the amount of carbon-14 in a piece of old wood for instance, and say that because there is only a certain amount left, the tree died 1000 years ago.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.

Coal, oil, and natural gas are supposed to be millions of years old; yet creationists say that some of them contain measurable amounts of C-14, enough to give them C-14 ages in the tens of thousands of years. Younger objects can easily be dated, because they still emit plenty of beta radiation, enough to be measured after the background radiation has been subtracted out of the total beta radiation. However, you now know why this fact doesn't at all invalidate radiocarbon dates of objects younger than twenty thousand years and is certainly no evidence for the notion that coals and oils might be no older than fifty thousand years.
