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. They are found in Europe somewhat later, from about 1 mya (0.7mya for Britain).The Palaeolithic is by far the longest period of humanity's time, about 99% of human history.One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.
Radiocarbon dating uses isotopes of the element carbon. Cosmic rays – high energy particles from beyond the solar system – bombard Earth’s upper atmosphere continually, in the process creating the unstable carbon-14. Because it’s unstable, carbon-14 will eventually decay back to carbon-12 isotopes.
Because the cosmic ray bombardment is fairly constant, there’s a near-constant level of carbon-14 to carbon-12 ratio in Earth’s atmosphere.
is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.
It can be used on objects as old as about 62,000 years.
