The first query we came up with was “life on other planets” because it was what the assignment told us to look for so our first instinct was to just look for those exact words in Google. The first result from this search was a Wikipedia article entitled “Extra-terrestrial life” leading us to decide on those words for our second query. On this second query one of the results contained the words “existence of aliens” which seems as a more to the point search query and more efficient for the assignment. We then decided that searching for existence of aliens could be excluding any other possible form of life that isn’t necessarily an alien since the term can be considered in several different ways. The query we came up with then was “existence of life in another planets”.
The four final sources we decided to use consisted in being one from each query (“life on other planets”, “existence of aliens” and “existence of life on another planets”). The sources consist of a Time article discussing the discovery of a very unusual organism on earth and the possibility of it being an extraterrestrial life form, a scientific blog on discussing the mathematical way in which we find the probability of finding life in other planets, an article compiling all the facts that support the idea of life actually existing on other planets and finally a Guardian article on a scientist’s claim of life existing on another planets. In comparison, query number 3 turned out as the most efficient due to the content of the source we found because of it (all the facts supporting the existence of life being true). Even though as a source it may not seem reliable the information on it is known to be valid and really convinces the reader on the probability of life existing on other planets being high.
