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.

But the method had one major flaw: it didn’t account for changes in the proportion of radioactive and non-radioactive carbon in the environment; and if these had changed, the estimate would most likely be wrong.

Many events can affect the levels of carbon-14 in the atmosphere, such as the burning of fossil fuel or the detonation of an atom bomb.

Carbon has unique properties that are essential for life on Earth.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

So, we have a “clock” which starts ticking the moment something dies.As scientists who study earth’s (relatively) modern history rely on this measurement tool to place their findings in the correct time period, the discovery that it is unreliable could put some in a quandary.For instance, remnants of organic matter formerly held up as solid evidence of the most recent, large-scale global warming event some 40,000 years ago may actually date back far earlier to a previous ice age.Prior to that, they had to depend on more rudimentary and imprecise methods, such as counting the number of rings on a cross-section of tree trunk.This all changed in the 1940s when US chemist Willard Libby discovered that carbon-14, a radioactive isotope, could be used to date organic compounds.
