Answer 2

It was in the late 1980s and early 1990s that Carl was fond of making this statement. He is most noted for using it on the Cosmos TV miniseries documentary. His quote refers to the fact that all of the carbon, sodium, potassium, iron, etc that make up the human body were created by stars during the process of stellar fusion long long ago.
With the exception of hydrogen and about 1/4 of the existing helium, all the other elements were created within a large star that eventually went supernova and blasted out all the heavy elements and the more common elements into space. After a long period of time, those elements mixed with more hydrogen and helium and coalesced into another star system and eventually formed planetary bodies.
Here, on earth, anything that is not hydrogen or helium was at one time formed within a star.

Answer 3

I believe it was in "The Lives of Stars [episode 9]" of the Cosmos series, and of course the corresponding chapter in his book.

Answer 4

I would assume from his series "Cosmos"
