This video describes the supernatural patterns in the Nazca of Southern Peru. The Nazca lines spread over the whole plain, which is unwatered and some even stretch for several miles. These patterns include the geometric figures, animals,plants and others. "The geometric ones could indicate the flow of water or be connected to rituals to summon water. The spiders, birds, and plants could be fertility symbols. Other possible explanations include: irrigation schemes or giant astronomical calendars."(Brown, Cynthia Stokes ,2007). Because these lines seem to be extraordinary claims, some people believe that Aliens did them. And the most famous and unexplained patterns look like an astronaut and airstrip. Also, people think the ancient Nazca people didn't have enough knowledge and technology, especially they did not have tools to check the patterns. As a result, Nazca lines become more mysterious. But many local Nazca people believe that their ancient made the lines. For me, I think these amazing patterns could be made by human. Because, I can't understand the purposes if the Aliens did them. Why the Aliens made them in our Earth? I agree that ancient Nazca people might made these lines to find water or hold pray rain activities because of their geographical locations. It could be coincidence or unaware to draw an astronaut and airstrip. Moreover, these pictures are imagined and called "astronaut" and "airstrip", they are subjective ideas. Whatever, I'm so interested in landscapes. I believe that we can find the real answers in the future. The reason I chose this topic because in chapter 2 I leart that we need find reliable evdiences to explor unknow things. I believe that I will remember to use scientific method to understand things in the future.
