　　The possibility existence of E.T 外星人英語作文

　　Do you believe in aliens really exist, no matter which planet they are living in? I do believe! In my imagination, extra-terrestrial is not as ugly and rude as the “prawn” in the movie “District 9”.To the contrary, I am convinced of a number of lovely and kind-hearted biological species who are living a happy life in certain remote planet maybe

　　doing some washing, shopping, exercising, creating and even exploring just like humans.

　　Besides my mild imagination, I will inform you of some reasons that E.T may exist.

　　Firstly, there are a lot of witnesses around the world, affirming that they chanced to have seen some strange things in the sky. Although most of them cannot hand in the credible evidence and some ufologists consider these strange things as natural phenomenon or human conducts, there are no apparent evidences to prove that existence of E.T is

　　impossible. Large numbers of people willing to believe that the UFO is the spaceship of extra-terrestrials.

　　Secondly, some astronomers pointed out that with a surprising number of fixed stars in the universe, there is a large possibility that we are not the only intelligent beings in the entire universe. Besides, with long-term efforts of scientists, we got an exciting news that they have been found seven outside world where might contain liquid water

　　which is essential to life. Addition, all of us can reach an agreement that life can thrive under extreme conditions.

　　Thirdly, the amazing “blue light-explosion” event sparked on

　　December 8, 2009 in Norway making some associations with the Aden Bay interstellar door open. When the mysterious interstellar door was open, some biological species which are not belonging to our earth would run out! Maybe it sounds like science fictions or movies, but scientists couldn’t give a reasonable explain to such blue light event.

　　Although for nearly half a century scientists have searched the sky for radio signals that clearly originated with intelligent life on another planet, some breakthrough discovers are really expected. Maybe just an intuitively opinion, I really feel we are not alone in the universe.
