Scientific American: How Scientists Could Tell the World if They Find Alien Life

      Today I read an article about aliens. It said that some astrobiologists believe that we will find evidence for alien life, because they believe that Mars show the evidence by the end of the 2030s. However, if the exist of aliens was proved, researchers cannot show this easily, because there are a lot of dubious claims and false alarms. They are trying making an experiment many times and these days, the researches are developing rapidly. Perhaps we can communication with aliens in the near future.
