不明飞行物(Unknown Flying Object)
We all know that we live in a complex world .Although the technics of the human beings are developing all the time ,we still got so many unsolved problems.Among all of this puzzles ,UFO is one of the most noticable things.
Now as everybody knows ,UFO is what we call Unknown Flying Object for short.For a period of time ,once we mentioned UFO ,we always communicate it with high-tech ,extra-terrestrials ,outter space culture and many other exciting things .
There are a lot of witnesses around the world ,affirming that they chanced to have seen some strange things in the sky .However ,most of them cannot hand in the credible evidence .That's a pity.
With the long-term efforts of the ufologists ,most of the incidents are finally considered as natural phenomenons or human conducts .Some so-called UFO is just a bird ,a plane ,a balloon or even a plastic bag .
Until now ,we haven't found any clues on real extraterrestrial civilization or supernatural phenomenon .But we are willing to see ,with the constant exertion of humanity,we will get more profound knowledge ,we will get to realize the essence of the world.We have the faith!
不明飞行物
我们大家都知道我们生活在一个复杂的世界上.尽管人类的科技无时无刻不在发展,但我们仍然有许多未解决的问题.在这些难题当中,UFO是最值得注意的之一.现在,正如每个人所知道的,UFO是不明白飞行物体的简称.在一段时期里,我们一提起UFO,就总是联系到高科技,外星人,地外文明和其他许多激动人心的事物.
世界各地有许多目击者声称曾经在偶然的情况下看到天空上有奇怪的飞行物.但是他们中的绝大多数无法提供可信的证据.这是一个遗憾.
在UFO专家的长期努力下,大多数的事件最终被证实只是自然现象或者是人类的行为.一些所谓的UFO只不过是一只鸟,一架飞机,一个气球,甚至只是一个塑料袋子.
我们还没有找到一点有关真正的地外文明和超自然现象的线索.但是我们愿意看到,随着人类的不断进步,人类一定能够获得更深刻的认识,了解世界的本质.我们有这个信心!
