Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.He claimed that it was capable of dating animal, plant and human remains of fairly “recent’ origin. As they say on Star Trek, we are all carbon based units.Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.­The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.Animals and people eat plants and take in carbon-14 as well.Worse still, sometimes they want to know how evolutionists use Carbon-14 to date dinosaur fossils!Radiometric Dating Technologies are presented to the public by evolutionists as utterly reliable clocks for dating earth rocks or biological materials. Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.Naturally occurring graphite occurs in two forms, alpha and beta.These two forms have identical physical properties but different crystal structures.
