Radiocarbon dating, which is also known as carbon-14 dating, is one widely used radiometric dating scheme to determine dates of ancient artifacts.In discussions of the age of the earth and the antiquity of the human race, creationists often assail perceived weaknesses in radiocarbon dating. Morris, for instance, wrote, "Despite its high popularity, [radiocarbon dating] involves a number of doubtful assumptions, some of which are sufficiently serious to make its results for all ages exceeding about 2000 or 3000 years, in serious need of revision." [Morris2000, pg. Radiocarbon dating is based on the fact that the interaction of cosmic rays from outer space with nitrogen atoms in the atmosphere produces an unstable isotope of carbon, namely radiocarbon.
Without these observations you cannot be sure that the time is valid.
A swimming race illustrates the simple principles involved in measuring time.

Anything that was once alive or that was produced by a living thing can be dated by using the radiocarbon method of dating.
This method, which received widespread attention in connection with the Dead Sea Scrolls, relies on the fact that all living things take in carbon, some of which is very slightly radioactive. To hear some people tell it, scientists have nearly absolute confidence in the dating methods they use.
But that's not really how it is when scientists are working in their labs.
To understand how the C-14 clock works and what processes are involved, let us consider the egg-timer.Scientists use carbon dating to determine when objects ceased to absorb carbon by measuring how much of the carbon-14 - which has a half-life of 5730 years - has decayed.But Beck and colleagues believe that the ratio of stable and radioactive carbon in the atmosphere may have changed considerably over the last 50 thousand years.By tipping the glass when the egg starts cooking, one learns when three minutes are up and the boiling should be stopped.One assumes that there is enough sand in the timer so that it takes three minutes for it to move from the top of the glass to the bottom of the glass.Thus creationists and others who invoke perceived weaknesses in radiocarbon dating as justification to cast doubt on the great age of the earth are either uniformed on very basic scientific facts, or else are highly being disingenuous to their audience.
