The scientific article deals with the problem of Existentialism, which has not lost its relevance in modern society. The scientific opinions of many scientists underlying the research were discussed, the psychological characteristics of Existentialism and its basic concepts were analyzed. Revealing the relationship between science and Existentialism, existentialists supplemented the reasoning: "from a scientific point of view, it is impossible to be silent about the existence of man" with an argument, analyzing the actions of the heroes of O. Bokey's story "Atau-Kere".  Although the existentialist did not investigate human existence from a scientific point of view, the existentialist in the work scientifically grouped the actions of the characters, demonstrating the psychological sequence of thinking.  He noted that the existence of images in one's own world is a complex psychological process. We tried to find ways to solve this problem by analyzing the actions of the heroes. That's the scientific basis of the article. Existentialism considers two types of human life: false and true. The first is the daily life of a person, and the next is his life, detached from social relations and independent of anyone, listening to his inner nature. The author in his article tried to prove that the way to solve this problem lies in spiritual wealth.
