Which carbon isotope is used for radiocarbon dating

Carbon-14 comes from nitrogen and is independent of the carbon-12 reservoir.

If even a small percentage of the limestone deposits were still in the form of living marine organisms at the time of the Flood, then the small amount of carbon-14 would have mixed with a much larger carbon-12 reservoir, thus resulting in a drastically reduced ratio.

Radiometric dating techniques are thus based on sound scientific principles, but rely on so many basic assumptions that Bible believers need not have their faith shattered by data derived from these techniques.

What do rock layers on the Earth's crust tell us about our origins and the age of the earth?

It's assumed that the clock was set to zero when the study material was formed.

This requires that only the parent isotope be initially present or that the amount of daughter isotope present at the beginning is known so that it can be subtracted.

Elements can be transported into a sample or leach out of a sample.

Scientists will reject theories about the age of the earth that do not conform to the norm.

c) Atmospheric carbon forms just 0.0005% of the current carbon reservoir—99.66% of the earth's carbon exists in limestone, 0.31% in oil and gas, and 0.02% in coal.

A further example from a lava flow off the coast of Hawaii shows similar discrepancies.

If dated with the carbon-14 method, the flow appears to be less than 17,000 years old, but dating with the potassium argon method gives dates of 160,000 to 43 million years.

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.
