Most of us have had the pleasure of lying on our backs and gazing up at the stars on a clear summer night. We pick out familiar celestial figures and hope to possibly catch a glimpse of a shooting star. But is it possible that there is more behind these pinpricks of white light that dot the heavens? It is estimated that there are around 100 billion stars in the Milky Way Galaxy alone and there are countless galaxies in the universe. With the vast endlessness of what we call space, there is a possibility of other life out there. Only four main atoms (carbon, hydrogen, oxygen, and nitrogen) make up 95 percent of life (Michaud 33). If one of the trillions of planets in the universe has these building blocks and the proper atmosphere it…show more content…

When Darwin released with work he was met with much controversy and was shunned by many (BBC). Even today, almost two centuries later, there are still people who deny his work and all of the scientific evidence behind it. But despite the initial resistance, Darwin’s theory of evolution is widely accepted among the world. His struggle for the acceptance of his theories was very similar to that of Galileo/ In the early 1960’s Francis Drake postulated the Drake Equation to determine the number of possible civilizations in existence. Because there are so many planets and solar systems in the universe, statistically some of them are inhabited by intelligent life. We have seen evidence of alien life in our own solar system (Michaud 162). NASA researchers have found traces of ice and water on Mars as well as bacteria that have survived on meteors in space. For the past fifty years the SETI project, also known as the Search for Extraterrestrial Intelligence, has been broadcasting signals in order to
