It's not real, you know.
A filmscore is written and pitched around to get backing to be made. If it is good (or hyped) enough to be successful in terms of box office receipts, they will consider making a sequel or a 'prequel' (which is when the story / narrative happens earlier in time than the original).
You will hear it said that Lucas et el always intended these sequels from the outset, but I somehow doubt it. Though I understand he had loose ideas for the first three films.
They had no idea that the original 'Star Wars' (note, no numbers or or tags) would be such a success, and as such, there is no "grand story" all written out ready. The latest films would have been written to fit in with the story thus far.
The first film made "Star Wars" ( or to give it the title on the original poster mock-up "The Star Wars" ) was only retitles "episode IV - A New Hope" when the first sequal came out ( episode V - the Empire Strikes Back ). Locas had always liked the Flash Gordon serials as a child, and had always wanted to do a series of films.
As the above answers say, he had no way of knowing that the film would be a runaway success.
