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.
Most authorities agree that C-14 decays at such a rate that half of it will be gone in approximately 5,730 years.
Many people also don’t realize that carbon dating (along with other radioactive dating methods) is based upon unverifiable assumptions.
The fact is, carbon dating can only be used to date things up to approximately 50,000 years old.
In fact, if an object contains (radioactive) carbon, this should be a clue that the object may not be any older than 50,000 years.
However, when one starts with the Bible and interprets the information received from carbon dating accordingly, one will soon learn that in no way does carbon dating disprove the young earth.
Misconception # 1: Carbon dating can be used to date objects that are millions or even billions of years old Carbon dating is one of the most popular radioactive dating methods used today.
C-14 is formed in the earth’s upper atmosphere as a consequence of cosmic radiation bombardment.
