    Is carbon dating the same as radiometric dating

    Thus it appears that God probably created those elements when He made the original earth.

    In contrast, radiocarbon forms continually today in the earth’s upper atmosphere.

    If carbon-14 has formed at a constant rate for a very long time and continually mixed into the biosphere, then the level of carbon-14 in the atmosphere should remain constant.

    If the level is constant, living plants and animals should also maintain a constant carbon-14 level in them.

    After radiocarbon forms, the nuclei of the carbon-14 atoms are unstable, so over time they progressively decay back to nuclei of stable nitrogen-14.3 A neutron breaks down to a proton and an electron, and the electron is ejected. The ejected electrons are called beta particles and make up what is called beta radiation. Different carbon-14 atoms revert to nitrogen-14 at different times, which explains why radiocarbon decay is considered a random process.

    To measure the rate of decay, a suitable detector records the number of beta particles ejected from a measured quantity of carbon over a period of time, say a month (for illustration purposes).

    Since each beta particle represents one decayed carbon-14 atom, we know how many carbon-14 atoms decay during a month.

    Chemists have already determined how many atoms are in a given mass of each element, such as carbon.4 So if we weigh a lump of carbon, we can calculate how many carbon atoms are in it.

    Through photosynthesis carbon dioxide enters plants and algae, bringing radiocarbon into the food chain.

    And as far as we know, it has been forming in the earth’s upper atmosphere since the atmosphere was made back on Day Two of Creation Week (part of the expanse, or firmament, described in Genesis 1:6–8). Cosmic rays from outer space are continually bombarding the upper atmosphere of the earth, producing fast-moving neutrons (subatomic particles carrying no electric charge) (Figure 1a).1 These fast-moving neutrons collide with atoms of nitrogen-14, the most abundant element in the upper atmosphere, converting them into radiocarbon (carbon-14) atoms.

    CARBON-14 IS CREATED (Figure 1a): When cosmic rays bombard the earth’s atmosphere, they produce neutrons.

    Instead, the radiocarbon atoms in their bodies slowly decay away, so the ratio of carbon-14 atoms to regular carbon atoms will steadily decrease over time (Figure 1c).

    Let’s suppose we find a mammoth’s skull and we want to date it to determine how long ago it lived.

      The Bible tells Christians that God is infallible, and Christians believe the Bible because they believe it was written by an infallible deity. So the start of our logical deduction must be the Bible, so let’s concentrate on that.
