Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.When a “date” differs from that expected, researchers readily invent excuses for rejecting the result.The common application of such posterior reasoning shows that radiometric dating has serious problems.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.
The rate of decay of N in 5,730 years (plus or minus 40 years).
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.
So, we have a “clock” which starts ticking the moment something dies.
Obviously, this works only for things which were once living.
