Arguments against carbon dating
As a result scientists can measure the ratio of normal carbon (C12) to radioactive C14 and use the ratio to estimate how long a plant animal or any products from them such as timber or cloth, has been dead.
The less C14 the older the organic matter is considered to be.
This argument is the same as their “the geological column doesn’t exist” argument.
Creationists think you should see the layers of rock like those of a cake, all over the earth, and apparently if there is any bending, that is proof the earth is young. No one expects there to be an unbroken record of the earth as creationists are claiming must exist for the earth to be over 4 billion years old, so the claim they are making is very misleading from the start.
When they die they cease taking in carbon of any kind.But Nature News et al still believe the world is very old, so what problems could they report for this well known method?To understand this we need to look at the method and its continually revisable history. Carbon dating is a method of estimating the age of organic matter by measuring the amount of radioactive carbon (C14) in the item.These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio.This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.
