　　Since human beings have existed in the Earth for millions of years, some scientists are curious about other intelligent forms in the universe. Some scientists attempt to communicate with these life forms. However, others believe it would be hazardous. In the following essay, both views will be explored as well as my personal stance.

　　On one hand, many scientists and evidence has proved that humans are definitely not the only creature in the universe, so contacting these intelligent life forms could be demanding. Specifically, other life forms also existed on other planets; some of them even have visited the Earth. For example, about several decades ago, an UFO has visited a small town of America, and they did not attack the humans. They could have destroyed the Earth if they had despicable plans. Therefore, contacting with these unknown creatures could help us to know the outer space better, so it would be beneficial for the humans to try to contact with these aliens.

　　In stark contrast, some other scientists believe that contacting with life forms would bring danger to the humans because we barely know them. To be precise, some scientists believe that these intelligent life forms could be smarter than us, and have more advanced technologies, people cannot win the war if they invade the Earth. Take films as example, as it describes in Independence Day, aliens invaded the Earth as they were aiming at the sufficient natural resources on earth and it is totally for their own interest. Their attack caused huge damage to the earth as human beings have no advanced weapon to fight back.

　　In my opinion, even getting in touch with aliens could bring dangers to humans, it is still worth trying as I believe the majority of them are seeking for peace of the whole universe and hostility is barely carried. Looking for other creatures in the vast universe is a big step for humans to explore the outer space. It could be a double-sword, bringing both opportunities and challenges. Whether aliens are dangerous dose not truly matter under this circumstance, what is more important is that earthman, us, have the ability and courage to take adventures in the unknown space and meet something new.

　　With advancement of societal technology, certain scientists work for looking for other intelligent life forms who may not exist on the earth such as aliens. While some people argue that contacting with them is likely to bring danger to human. Therefore, the essay aims to critically discuss both views and come up with my own opinion.

　　That a number of researchers try to find other planets’ living species has to be admitted that pursing that curiosity is one of mankind’s nature. Additionally, by exchanging ideas with aliens about historical progression and academic discussion and so on, mankind’s world has the opportunity to make immense progress in modern technology by giving inspirations to scientists for pushing the frontiers of science which may solve particular thorny issues such as environmental pollution. On the other hand, as far as some researchers are concerned, it lays a solid foundation for people to possess an improved quality of life who live on other planets in order to avoid diseases and disasters brought by serve atmosphere pollution and doomsday respectively.

　　While, simultaneously, others claim that touching with aliens probably breaks seemingly peaceful earth and brings unexpected danger. Firstly, it is likely that being greedy, exploitative and violent, aliens are searching for somewhere to harvest for water, minerals and fuel, contributing to meeting unprecedented risk by telling them the man’s existence. Furthermore, people know nothing of extraterrestrial intelligence intentions and capabilities so it is impossible to predict whether they will be benign or hostile. For example, earthlings will may be slaughtered and enslaved as colonized countries in the past time.

　　From a personal perspective, earthlings can try to search for other unique life forms in various planets, but without promising to guarantee human’s lives, it would not better send messages to aliens and disturb their daily lives.

　　Our imagination about beings on other planets has never stopped and reached its climax in such movie series like “Star Wars” and “Star Trek” in 1960s and 1970s. If other life forms do exist, an idea I strongly support, should we, as human beings on the Earth, try to reach out and communicate with them?

　　A lot of people do not like the idea of sending messages to aliens “out there”. According to their theory, trying to establish communication with other life forms is extremely expensive because it entails designing complex equipment and apparatus. This will consume tons of money, which should be spent solving more practical problems like medical care or education. More importantly, as these people would claim, once they receive our messages and know about our existence, the aliens may invade the Earth and eliminate us all, just like what they do in many movies and science fiction.

　　There are others who are very enthusiastic about reaching out for aliens on other planets. They are interested in how these different life forms survive and believe their more advanced technology may well help us human beings solve our existent problems. Having been living in the universe as the only intelligent being for too long, many people find it very attractive to reach their brothers and sisters from other planets. It is significant for another reason, too. As the Earth will surely die and disappear into the black hole as many scientists have speculated, we need to be known by our siblings on other planets so that when that day eventually does come, our future grand, grand children will not perish.

　　Personally, I do not think much of the “danger” theory. If the aliens are less developed than us, they cannot be a threat to us even if they want to; if they are more developed and civilized, the probability that we are killed by them is still lower. Once the xenophobic danger is removed, I believe most of us will welcome the idea of communicating with the intelligent forms outside the Earth, because they can provide us with the much desired companionship and may save us when the Earth expires.

　　When it comes to the issue about the possibility of aliens’ existence on other planets, some people argue that there should be communication between human beings and other creatures if they really exist, but others believe that it may lead to some potential risks for human beings to communicate with unknown life forms.

　　On one hand, mankind may benefit from communicating with other creatures if they own advanced technologies. It is true that human beings have developed numerous technologies currently, but some aspects, such as space exploration, still need to be improved. If other planets possess technologies human beings do not have, maybe they could assist us to make a progress. Thus, sending messages to them could allow human beings to have more technologies from the universe possibly.

　　On the other hand, getting in touch with aliens may be detrimental to human beings since they may invade the earth. Countries on the earth will fight with each other because they need to acquire more resources. Similarly, if alien civilization also intended to reap some profits from the earth, space wars would be an inevitable consequence. Therefore, in order to maintain a peaceful life on the earth, human beings should be really cautious about sending messages to outer space.

　　From my own perspective, exploring space will be a compulsory task for mankind sooner or later, but scientists should be patient before they make more breakthroughs. After all, human beings are just potent to send their astronauts into outer space for limited time and our technology is still not so mature. Also, there still exist all kinds of conflicts among countries on the earth and developing domestic economy should be the top priority for most governments to improve their citizens’ life quality. Thus, human beings may not be prepared to welcome alien civilization in the current era.
