2001 : A Space Odyssey

As the title is really odd enough, I thought the first part I watched today was as idiosyncratic as the title. I did not recognize that the movie file actually contained subtitle because..... there was no line until the creepy apes ,that I would rather deny me [should this be I?]being their descendant, made this loud noise to scare off other apes. It was not until I saw one of the ape using a bone as a tool that I realized I have heard of this movie before. I remember it quite accurately; it was when I was in prom school to study for korean university entrance, and there was a short cartoon that referred to this movie in a practice test. I recall that the answer to that problem was that thanks to the ability we could use a tool, we evolved since then and came this far- to space shuttle. I do not know where on earth this story is going, but I have to say that I am very interested.
