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.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.

With less carbon-12 to dilute the carbon-14 continually forming from nitrogen in the upper atmosphere, the ratio of carbon-14 to carbon-12 in the atmosphere would increase.

When granite rock hardens, it freezes radioactive elements in place.

The most common radioactive element in granite is Uranium-238.

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.

If the atmosphere's ratio of carbon-14 to carbon-12 has doubled since the flood and we did not know it, radiocarbon ages of things living soon after the flood would appear to be one half-life (or 5,730 years) older than their true ages.
