  The lightest elements (hydrogen, helium, deuterium, lithium) were produced in the Big Bang. Nuclear fusion in stars converts hydrogen into helium in all stars. In large stars further reactions convert helium to carbon and oxygen take place in succesive stages of stellar evolution. In the very massive stars, the reaction chain continues to produce elements like silicon up to iron. Elements heavier than iron are formed by a supernova.

  It’s all from the stars which is hard to imagine isn’t it?!
