The purpose of life remains a variable for humanity. There are three possible choices for this variable: no purpose, a purpose, or the purpose. These choices can be analogous to nihilism, existentialism, and belief in a divine being, respectively. But how should one live? From a nihilistic, existentialist point of view or simply out of pure faith? The answer: the latter. However, humans tend to believe that their thinking is rational, but one can only say that one's thinking is rational if one knows everything. According to Jesús Mosterín, “Human beings are not rational by definition, but they can think and behave rationally… depending on whether they apply… the thoughts they accept” (Infosources). In the context of these words, humans create what they believe to be rational based on their knowledge, but in reality humans cannot be rational because they do not possess omnipotence. Since humans are irrational, there must be a rational being who knows the explanations to all questions; everything must have an opposite. With this, nihilism and existentialism are creations of the human mind that make it irrational; both of these philosophies do not explain the foundations of our existence. Rather they are simply a substitute for what humans cannot understand. Hence, people should live by faith in a divine being since it is rational while both nihilism and existentialism are irrational. The philosophies of nihilism and existentialism coincide in that they both rely on human interpretation for the purpose of life. It is a widely accepted definition that nihilism “is the belief that all values ​​are baseless and that nothing can be known or communicated” (Dr. Alan Pratt).
