And carbon dating

Some scientists argue that the magnetic field of the earth has declined over time.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 rock sample from Nigeria was dated at 95 million years by the potassium-argon method, 750 million years by the uranium-helium method, and less than 30 million years by the fission-track method.If the clock is not set to zero when a deposit forms, then there can be no starting point from which to calculate the age of a deposit.They will argue that the clock was not reset if the age is too old, or that isotopes were selectively removed if the age turns out to be too young.

Scientists will reject theories about the age of the earth that do not conform to the norm.We could put forward the following counter arguments to the constancy of these assumptions: a) The constancy of cosmic ray bombardment might be questioned.The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .It is assumed that we are dealing with a closed system—no loss of either parent or daughter elements has occurred since the study material formed.No scientist can guarantee that any sample can be considered a closed system unless it was isolated from its environment when it was formed.

It is, therefore, not surprising that many misconceptions about what radiocarbon can or cannot do and what it has or has not shown are prevalent among creationists and evolutionists - lay people as well as scientists not directly involved in this field.
