For this reason, I will have to bite the bullet and accept that it is reasonable to assume the decay rate is constant (even though I give this assumption, this doesn’t mean the decay rate is constant.

Rather I am conceding due to no current evidence for the contrary).

Because C-14 is radioactive, it is unstable, and is constantly decaying back into N-14.

Since C-14 is so well distributed in the atmosphere, it is assumed the same ratio that is in the atmosphere will also be in an organism.

How carbon dating is supposed to work Once an organism dies, its C-14 decay is no longer being replaced by intake.

After about 8 half-lives, the remaining amount of C-14 (if there is any remaining) is too small to be measured.

For this reason, it is simply impossible for carbon dating to give dates as old as millions of years. Closed systems, void of any contamination and without loss of the parent element (C-14) or daughter element. Known amounts of parent and daughter elements present from the beginning. If the decay rate of C-14 were not always constant, then this would be devastating to the technique's credibility.
