If this claim is true, the biblical account of a young earth (about 6,000 years) is in question, since C dates of tens of thousands of years are common.1 When a scientist’s interpretation of data does not match the clear meaning of the text in the Bible, we should never reinterpret the Bible.
God knows just what He meant to say, and His understanding of science is infallible, whereas ours is fallible.
So, if you're trying to use his to date dinosaurs, just stop.
One is for potentially dating fossils (once-living things) using carbon-14 dating, and the other is for dating rocks and the age of the earth using uranium, potassium and other radioactive atoms.
The atomic number corresponds to the number of protons in an atom.
So we should never think it necessary to modify His Word.
Genesis 1 defines the days of creation to be literal days (a number with the word “day” always means a normal day in the Old Testament, and the phrase “evening and morning” further defines the days as literal days).
Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.
There are two main applications for radiometric dating.
The number of protons in the nucleus of an atom determines the element.
For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.
Now one thing that it's important to keep in mind about carbon dating is that this is a really small number. The abundance, the natural abundance is already very small. You can usually date something that's under about 40 or 50,000 years old using this technique.
