That is understandable from the standpoint of design, because proteins are the backbone of chemical machinery inside a cell.

  7. How accurate are Carbon-14 and other radioactive dating methods? See this page in: , , People who ask about carbon-14 14C dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the. Clearly, such huge time periods cannot be fitted into the without compromising what the Bible says about the and the —the reason came into the world See. This only makes sense with a time-line beginning with the thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods. How the carbon clock works Carbon has unique properties that are essential for life on Earth. One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or 14C, or radiocarbon. Carbon-14 is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere. These displaced neutrons, now moving fast, hit ordinary nitrogen 14N at lower altitudes, converting it into 14C. Unlike common carbon 12C , 14C is unstable and slowly decays, changing it back to nitrogen and releasing energy. This instability makes it radioactive. Ordinary carbon 12C is found in the carbon dioxide CO 2 in the air, which is taken up by plants, which in turn are eaten by animals. So a bone, or a leaf or a tree, or even a piece of wooden furniture, contains carbon. When the 14C has been formed, like ordinary carbon 12C , it combines with oxygen to give carbon dioxide 14CO 2 , and so it also gets cycled through the cells of plants and animals. Because 14C is so well mixed up with 12C, we expect to find that this ratio is the same if we sample a leaf from a tree, or a part of your body. In living things, although 14C atoms are constantly changing back to 14N, they are still exchanging carbon with their surroundings, so the mixture remains about the same as in the atmosphere. However, as soon as a plant or animal dies, the 14C atoms which decay are no longer replaced, so the amount of 14C in that once-living thing decreases as time goes on. Obviously, this works only for things which were once living. It cannot be used to date volcanic rocks, for example. The rate of decay of 14C is such that half of an amount will convert back to 14N in 5,730 years plus or minus 40 years. Anything over about 50,000 years old, should theoretically have no detectable 14C left. That is why radiocarbon dating cannot give millions of years. In fact, if a sample contains 14C, it is good evidence that it is not millions of years old. However, things are not quite so simple. First, plants discriminate against carbon dioxide containing 14C. That is, they take up less than would be expected and so they test older than they really are. Furthermore, different types of plants discriminate differently. This also has to be corrected for. This would make things which died at that time appear older in terms of carbon dating. Then there was a rise in 14CO 2 with the advent of atmospheric testing of atomic bombs in the 1950s. This would make things carbon-dated from that time appear younger than their true age. Measurement of 14C in historically dated objects e. Accordingly, carbon dating carefully applied to items from historical times can be useful. However, even with such historical calibration, do not regard 14C dates as absolute because of frequent anomalies. They rely more on dating methods that link into historical records. Other factors affecting carbon dating The amount of cosmic rays penetrating the Earth's atmosphere affects the amount of 14C produced and therefore dating the system. The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy. The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere. A stronger magnetic field deflects more cosmic rays away from the Earth. Overall, the energy of the Earth's magnetic field has been decreasing, so more 14C is being produced now than in the past. This will make old things look older than they really are. Also, the would have greatly upset the carbon balance. The flood buried a huge amount of carbon, which became coal, oil, etc. Total 14C is also proportionately lowered at this time, but whereas no terrestrial process generates any more 12C, 14C is continually being produced, and at a rate which does not depend on carbon levels it comes from nitrogen. Unless this effect which is additional to the magnetic field issue just discussed were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages. Creationist researchers have suggested that dates of 35,000 - 45,000 years should be re-calibrated to the biblical date of the flood. Also, volcanoes emit much CO 2 depleted in 14C. Since the flood was accompanied by much volcanism see , , and , fossils formed in the early post-flood period would give radiocarbon ages older than they really are. In summary, the carbon-14 method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully. It does not give dates of millions of years and when corrected properly fits well with the biblical flood. Other radiometric dating methods There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks. These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains. For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc. These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification. The isotope concentrations can be measured very accurately, but isotope concentrations are not dates. There are patterns in the isotope data. There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. However, there are s
