The key questions then are: Has the atmospheric ratio of carbon-14 to carbon-12 changed in the past, and if so, why and how much?The assumption usually made, but rarely acknowledged, is that the ratio of carbon-14 to carbon-12 in the atmosphere before the industrial revolution has always been the sameabout one in a trillion.Plants take in carbon dioxide, incorporating in their tissues both carbon-14 (unstable) and normal carbon-12 (stable) in the same proportion as they occur in the atmosphere .Carbon-14 then moves up the various food chains to enter animal tissueagain, in about the same ratio carbon-14 has with carbon-12 in the atmosphere.When a living thing dies, its radiocarbon loss (decay) is no longer balanced by intake, so its radiocarbon steadily decreases with a half-life of 5,730 years.If we knew the amount of carbon-14 in an organism when it died, we could attempt to date the time of death.Half of it will decay in about 5,730 years to form nitrogen.Half of the remainder will decay in another 5,730 years, and so on.

One limitation is that the radiocarbon technique dates only material that was once part of an animal or plant, such as bones, flesh, or wood. To understand the other capabilities and limitations of radiocarbon dating, we must understand how it works and consider the flood. However, roughly one in a trillion carbon atoms weighs 14 atomic units. It is also called radio carbon because it is radio active (but not dangerous).They concluded that the helium in the rock was 100,000 times more plentiful than it should have been if the rocks were really 1.5 billion years old.They concluded that their findings are consistent with an Earth that is about 6,000 years old.As our knowledge continues to grow, what we know continues to be in agreement with Scripture.

Radiocarbon ages less than 3,500 years old are probably accurate.

Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
