Radiocarbon dating of fossils taken from caves

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?

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.Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).Most carbon-14 quickly combines with oxygen to form radioactive carbon dioxide, which then spreads throughout 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.

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.

Outside the range of recorded history, calibration of the 14 clock is not possible.

This means the above calculations are only evolution speculation and NOT backed up by real science.

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