Is carbon 14 dating reliable
Furthermore, as in all radiometric dating methods, there are assumptions. So, as you pour water into the barrel, it is also leaking out of the barrel.
Here’s the main one: Imagine filling a barrel with water. Eventually you’ll reach a point where the water entering the barrel is leaking out just as fast. Unless you decrease the amount of water leaking from the barrel, or increase the amount going in, the barrel will reach equilibrium.
That, of course, is a drop in the bucket compared to the “millions and billions” of years being thrown about by evolutionists.
This method can only be used on organic substances—that is, things that used to be alive.
However, cosmic radiation is constantly colliding with atoms in the upper atmosphere.
The ratio of carbon-12 to carbon-14 at the moment of death is the same as every other living thing, but the carbon-14 decays and is not replaced.
These are also known as radiocarbon atoms, and they are unstable because they decay (which means they are radioactive) into a different type of atom–nitrogen.
There are many more stable carbon atoms in the atmosphere than unstable ones.
A question I am often asked at seminars relates to the radiocarbon method of dating old things.
People have been told that carbon-14 is a good indicator of an old earth and therefore supports the evolutionary idea. The assumption that carbon dating supports a very old earth is outdated.
