"One night about 60 years ago, physicist Enrico Fermi looked up into the sky and asked,’ Where is everybody?’" We have been trying to find the answer to that question ever since. There are many theories about extraterrestrial beings or Aliens, but none have been proven, yet we keep searching for them. Some people feel like this is a waste of time and money, but others feel this is getting us closer to understanding the universe and life itself. Should we keep spending so much on trying to find extraterrestrial intelligence, or should we spend that time and money on something more substantial?

There isn't any solid proof that aliens are real, but we keep searching for them because if we did find life outside of our planet, we could have many of our questions answered. Frank Drake an astrophysicist and chairman emeritus of the California-based SETI, Director of the Carl Sagan Center for the Study of Life in the Universe, and a Professor of Astronomy at Cornell University. Has no doubt about the existence of intelligence outside of our planet. That's why SETI was formed. SETI, Search for Extraterrestrial Intelligence, is a scientific investigation that began in 1984; in 2012, SETI cost $2 million per year to keep, the institute has approximately 100 scientists. In July 2015, another program was formed, Breakthrough. It will last ten years with a budget of $100 million. It's searching for intelligent extraterrestrial communication (SETI Institute).

There are so many planets in our galaxy, and earth is the only one that accomplished life. It seems practically impossible. Our planet might not be exactly the same as another. Still, creatures evolve to adapt to their circumstances, and if there is a planet similar to our own, life on that planet might have been able to form, adapt and evolve to survive in that environment. 

Some scientists believe we spotted the first known interstellar small body with the Gemini North Telescope on Hawaii's Mauna Kea; Oumuamua. It has been discovered by Pan-STARRS1, and it offers a rare opportunity to explore the planetary formation processes of other stars. As soon as it was discovered, astronomers worldwide tried to collect information on its nature. With this, we are one step closer to discovering extraterrestrial intelligence!     There isn't any proof of intelligent life in the galaxy, but we keep searching for it. We haven't even found bacteria let alone developed life, but astronomers and physicists such as Drake, Sagan, and Morrison search for intelligence outside of earth anyway. In contrast, most leading experts in evolutionary biology, such as Simpson Francois and Mayr, are certain that our planet is most likely unique in hosting intelligent beings. These scientists argue that even if we develop existence in the galaxy on any other planet than ours, the chance of its evolution is near to nothing. The number of evolutionary pathways that lead to organisms developing into intelligent beings is minuscule. The probability of developing creatures that have achieved interstellar communication is less than ten to the tenth power, so it would only make sense if we are the only intelligent creatures existing in our galaxy (Frank J.Tipler). 

Other writers such as Fermi, Dyson, Hart, Simpson, and Morris have expressed their doubts about intelligence outside of earth, concluding that it doesn't exist. If such creatures did exist and did achieve interstellar communication, they would have also achieved space travel, and if that were the case, we would have already spotted them in our galaxy. 

There are many more things that we could spend our time on. Some people say that we should focus on more important matters, such as discovering our ocean. The ocean covers about 70% of our planet, and we explored less than 20% of it. Instead of spending our time trying to find something that hasn't even been proven, we should explore our planet. 

Even though there are still many things we don't know about our planet, I believe that we should keep searching for extraterrestrial intelligence. It would be great if we could communicate with other creatures outside our species. We may not have any evidence of their existence. Still, I think that it's impossible for us to be alone, we may not find anyone in our galaxy, but there are millions of galaxies in the universe.
