Task：Some scientists believe that intelligent life forms may exist on other planets and some want to send messages to contact them. Others think it is a bad idea because these life forms may be too dangerous. Discuss both views and give your own opinion.
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.
