Giải chi tiết:

Scientists have found evidence to prove the presence of extraterrestrial life so far. Even though many newspapers talked a lot about UFOs, I do not believe in the existence of them. The first reason why this seems unimaginable to me is there might be things that were easily mistaken. For instance, flying saucers which people saw could be aircraft models, balloons, clouds, or even tricks of light. Secondly, there are not enough photos which demonstrate clearly the shapes of the UFOs. Can we really trust in some pictures of faint lines which are claimed to be the UFOs? Furthermore, should there be UFOs, there must be traces of their landing. However, what we have got so far are not obvious enough to leap to a conclusion. Probably, UFOs are just imagination of some exaggerated writers who crave for shocking news to write about to earn media attention. Who can say?
