First well working civilizations in our world! (The once we have developed from)

Warning: The following text is all true and it may also have some words like school or talk about it. If you have an faint heart... ah whatever lets just get to the point. Today at school we watched movie called "Guns, Germs and Steel" or at least 45 minutes of it. It was based on book called "Guns, Germs and Steel" written by Jared Diamond and the book was true of course. The movie was about early civilization which took time about 30,000 years ago or something I don't remember quite well. So some archeologists found a small village which they predict is the first village ever. After the first village was build they started to use resources to invent more things like do farming I mean they actually invented farming. With resources they also developed technology and soon they had created metal or steal. Then after watching one part of the movie we had to make a headline that best describes what we saw in it. My headline was: "When technology goes further" and I believe that was pretty good one. Anyway I got a homework to response for that headline and expand it. Well I would respond that my headline was quite ok and right because that's what the movie showed me and so on. Then I would expand it with this. When technology goes further it starts from nothing and soon you have invented something important like steel. But I think that's about it...
