Question: In the "first timeline", Marty's father is a loser. He has never hit Biff. Marty goes to the past, and when he's going to 1985, he says that to Doc. He returns to the "new" 1985, where his father is successful, and he has hit Biff. He sees himself going to 1955, and that Marty is about to do everything that Marty did in the movie. But here's a question: that Marty lives in the "second timeline", where his father has hit Biff. Why then, in the past, he would say that his father has never hit Biff in his whole life?

Answer: Another good example for a parallel timeline being created, which the writers/story denies. but while the "second Marty" has no reason to tell Doc that his father never stood up to Biff. His comment is of no significance to the outcome of events. The important change in the past was Marty being in George's spot and then having to fix things.

Answer: I see two possible explanations. One is simply that the improved George McFly never told Marty the story about how he clocked Biff, perhaps to keep Marty from getting into fights himself. The other explanation is that the 1955 Marty went back to had not yet changed before he came back to the improved 1985. As the slowly-changing photograph illustrates, changes in timelines can be very gradual. Therefore, the only version of 1955 we are able see is the 1955 that the Marty of the original 1985 went back to.
