This isn't an agreement with the parents comment about Tesla but re-usable rockets weren't invented by SpaceX. The idea existed for a while and various projects got to different stages. Including a functional 'McDonnell_Douglas_DC-X'.
The project got taken over by NASA and the budget cut before being axed. You really do sound a bit too fanatical and should probably question more instead of accepting companies as entirely revolutionary.
