Radiocarbon dating of fossils taken from caves
Actually, that ratio may have been quite different.
For example, a worldwide flood would uproot and bury preflood forests.
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.
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
This means the above calculations are only evolution speculation and NOT backed up by real science.Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.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.Radiocarbon ages do not increase steadily with depth, as one might expect. In other words, the concentration of carbon-14 is unexpectedly low in the lower organic layers.As one moves to higher and higher layers, this concentration increases, but at a decreasing rate.
