if stars are fusion reactors of the energy released by the fusion of two hydrogen atoms into helium,
1. how and why is it that astronomers and physicists say that stars are the thing that makes all other elements? for example, how can a star make carbon, sodium, gold, or oxygen?
2. then how would such elements get dissipated throughout solar systems?
3. where are the elements other than hydrogen? are those elements only on planets, and if not, where else do they exist in universe (other than inside of black holes)?
4. and how does a star control how planets are made?
5. how does a star cause a certain balance of certain elements to exists on one given planet and not on another? (for example, on earth, but not so much on jupiter)?
6. and one other thing: how does hydrogen eventually form into cloudlike structures in space, eventually making nebulae whereby [where] stars get born?
7. how are we so sure of all of this? what empirical proof do we have?
