It is considered by some researchers that there might be other kinds of 
 in another part of the world and it would be beneficial for us to contact them. 
, others believe that they might be dangerous and may harm 
 on 
. In my opinion, I think that that intelligent 
 might have violent attitudes which may harm 
 on 
. 
 of all, many believe that those species could help us solve few mysteries regarding 
 and the galaxy. 
,  if there is 
 on the other side of the universe, 
 they might assist 
 in solving some complex problems 
 as the gravitational force of 
, how much it differs in comparison to other 
, and much more. 
, that intelligent 
 might aid us to overcome shortages of water and other renewable sources by providing us resources from their 
. In 
 way, the 
 would be able to survive its diversity much longer. 
 to 
, 
 nowadays primarily based their research on hypotheses, but with the help of other species, they might conduct research based on facts. 
, 
 collaboration would convert few illusions into reality. To illustrate 
, a science fiction 
 was released 
 year, which showed how the scientist from 
 collaborated with extraterrestrial 
 to prove some of the theories. Not only 
 collaboration helps in solving issues, but it 
 led to a rise in tourism. The 
 showed an increase in travel to other 
 via space shuttle and boasting of the world's economy due to aliens. So, the beliefs of many 
 might come true if another 
 exists and they aid in researching the universe.
, one of the most significant disadvantages is that they might be violent and aggressive in behaviour. It may be plausible that those living beings consider us as dangerous, which can instigate them to attack us. In 
 way, it will lead to more chaos and violence,  which may be harmful to people and the universe. 
, it may be possible that they have some evil intention to destroy 
 on 
 or to steal away 
’s resources, or maybe they could treat human beings as guinea pigs to conduct their experiment on people. 
, in the “ alien” 
; it was showed that aliens couldn’t digest the fact that 
 has its own 
. Due to 
, they planned to eradicate 
 on 
 via nuclear resources. That 
 depicted how a catastrophe would be if all 
 turns into reality. 
, 
 may happen in real 
, too, so one should be cautious before considering 
 thoughts of collaboration.   
To conclude, even though many 
 consider other 
 as helpful, there is a much greater probability that those living beings might harm people. 
, the government should restrict many institutions' research to save the planet and save 
 on 
.
