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.
Therefore, a radiocarbon year would not correspond to an actual year.
As explained in recent measurements show that the ratio of carbon-14 to carbon-12 has been building up in the atmosphere.
However, for the last 3,500 years, the increase in the ratio has been extremely slight.
Radiocarbon dating of vertical sequences of organic-rich layers at 714 locations worldwide has consistently shown a surprising result.
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.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.The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.
