According to the Law of Conservation of Mass, matter can neither be created nor destroyed. This means that all atoms are recycled over time. Which in turn means that our own atoms are ancient as well. One’s skin could have carbon in it from a meteorite or from a trilobite thousands of years old, and your blood could contain hydrogen from earth’s original atmosphere.
