The main topic in the documentary entitled, “Cave Of Forgotten Dreams” by Werner Herzog, is the importance of findings within a cave. One way that explains the importance is the cave paintings that are found on the wall. Another way was how the inside of the cave looked, the structure of the cave. A third way that the findings were important, is how they saw the type of animals and people that used to stay within the cave many years ago. In conclusion, understanding everything about the cave, gives us more knowledge of how life used to be many years ago.
