We understand that nuclei heavier than hydrogen are made through nuclear fusion. The most common "machines" that operate on this principle are stars. People and other living things, and most everything on the Earth, including the Earth itself, has "star stuff" as its basis. Stellar nucleosynthesis is the creation of helium and all the heavier nuclei from hydrogen. Note that only elements up through iron are created in "normal" fusion. It takes a super nova to create the trans-iron elements. It was the late Carl Sagan who used to so often say that we are made of star stuff.
