This is what my born again Christian friend tries to explain to me everytime we talk about evolution.
In the past I've held my ground quite firmly on this topic, but as of recently he has made some claims from some "scientific journals" that carbon dating may not be as accurate as thought, and that it is misleading.
With that said, however... Answers to Creationist Attacks on Carbon-14 Dating Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.
Therefore it should come as no surprise that creationists at the Institute for Creation Research (ICR) have been trying desperately to discredit this method for years.
I may have evidence, but that evidence may have been faked.
That's far enough to prove the 6000 years Biblical account to be wrong.
Elite Engineer - Note that it's hard to use logic and reason to argue someone out of a position at which they arrived using neither.
It is based on physics, specifically about radioactivity, and radio active elements are used in nuclear reactors.
If you deny the science of radioactivity, then you also deny nuclear reactors can produce electricity.
As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.
