Cosmicism

Cosmicism is the belief that humanity is just a natural occurrence within the Galaxy and nothing practically special. It focuses on logic and atheism above all and the respect for the unpredictability of nature. It is Existentialism taken to the extreme as all that humanity's destiny is chosen for them and every individual's life happens the way it does by the uncontrollably tides of fate.

You are born, live, and die. Your fate is sealed and you must accept how it must be for you are one grain of sand in the Galaxy.
