    Real question: Is the decay of uranium the only natural way to produce lead? If so TIL.

      No. Nucleosynthesis of lead within stars generated from supernovae make up the bulk of the existing lead on Earth. Uranium decay does provide some additional lead inventory but would be fairly small in comparison.

      But the presence of it in the first place within second generation stars proves that lead is billions of years old.
