Science fiction film is always favored by the audience. Every year, the hottest movies must belong to the theme that search the universe. Aliens in the movies have been described into some evil creatures that try to destroy the earth. No one can make sure whether there is another life exists in the universe, but the movies probe this question all the time. I have seen many documentaries about searching aliens. Though the scientists never saw the real life, I still believe that life besides human beings, life must exist in the universe. The earth is just one of the small galaxies in the infinite universe and we know little about it. The searching of another life someday will make breakthrough and we can see what else besides earth, or we will find the creature with high IQ.

科幻电影总是深受观众的青睐。每年最热门的电影一定属于探索宇宙的主题。在电影中外星人被描述成邪恶的生物，试图毁灭地球。没有人能确定在宇宙中是否存在另外的生命，但是电影一直在探索这个问题。我看了很多关于寻找外星人的纪录片，虽然科学家们从未在现实中见过外星人，但我仍然相信除了人类之外，宇宙中存在另外的生命。地球在无限的宇宙中只是一个小星系，我们对它知之甚少。搜索另外的生命总有一天会得到突破，我们会看到在地球之外还有什么，或者发现高智商的生物。
