Radiometric dating vs carbon 14
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.
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.

We thank you in advance for partnering with us in this small but significant way. All methods of radioactive dating rely on three assumptions that may not necessarily be true: It is assumed that the rate of decay has remained constant over time.
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.
It's assumed that the clock was set to zero when the study material was formed.
