Most of us have seen the famous movie ET, which is a story about an alien. Actually, newspapers have also reported that people have seen real creatures like aliens and flying machines called UFOs several times in the daily lives. If there are no aliens, how can people describe their experiences so vividly? Furthermore, compared to the rest of the universe, the ability of we human beings is so limited that we surely haven’t found out about all of its mysteries. Therefore, with the development of science and our hard work, maybe we will confirm the existence of aliens in the near future by discovering some new evidence. In short, please believe that aliens surely exist in the universe. 本文来源：https://www.wddqw.com/doc/9e56c63dab114431b90d6c85ec3a87c240288ad3.html
