It cannot be used to date volcanic rocks, for example.The rate of decay of N in 5,730 years (plus or minus 40 years).Overall, the energy of the Earth's magnetic field has been decreasing, so more C is being produced now than in the past.
So, we have a “clock” which starts ticking the moment something dies.
Obviously, this works only for things which were once living.
C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.
People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.
It does not give dates of millions of years and when corrected properly fits well with the biblical flood.
There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks.This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.Anything over about 50,000 years old, should theoretically have no detectable C.We will deal with carbon dating first and then with the other dating methods.Carbon has unique properties that are essential for life on Earth.When a “date” differs from that expected, researchers readily invent excuses for rejecting the result.
