The article analyzes the conceptual certainty of the cosmic basis of humanexistence. Man is considered as an organic and active part of the Cosmos. Moreover, human personality manifestations are various, they are not reduced to any one way of being. They realize the connection of a man with the environment, with other people, with himself in different being states and, finally, with Cosmos in its universality. The last connection is carried out at the spiritual level in the form of knowledge and other spiritual forms.The author focuses on the fact that the spirit is the space in which the human personality is formed as a spiritual being. Spirit, in turn, is associated with the cosmic existence of man, because it is a specific formation, which accumulates the spiritual energy of mankind, above its manifestation, through which the process of self-development of the Cosmos is carried out.By asserting itself in the world, a person is constantly searching foropportunities to take root in it. The universe opens boundless horizons before it, but they must be understood, mastered, appropriated. This is what determines the constant spiritual exploration, measurements of infinity, polyphonic silence voiced by means of philosophy.In theoretical explanations of the appearance of human, there are more and more people who, first of all, connect human existence with space. In antiquity and the Middle Ages, man was determined by the fact that he belonged to the general structure of the space. Thus, for example, the problem of all neoplaton anthropology, starting with Plato and Proclus, was the ratio of the human mind to the world mind.The famous medieval thinker Ibn Gebirol expressed confidence in the identity of human and the universe. In Ukrainian philosophical thought, the idea of human cosmic origin is essentially traditional. It is most vividly expressed by Hryhori Skovoroda. The relationship between macro- and microcosmos is constantly being clarified on the pages of his works.The fundamental difference between the philosophers’ desire for wisdom and the scientists for erudition is hidden in their relation to knowledge. The undervaluing of philosophy and philosophical knowledge has led to the fact that modern research in cosmology, biology and neuroscience is completely unrelated and does not enrich each other through explorations. In the philosophical tradition, knowledge is the way to the Divine, or, in the terminology of Modern philosophy, it is the way to the ontology of the cosmos. Thus, there’s a lot of evidence of human cosmic origin and cosmic connections.By space in this case, we mean the universe, what is beyond it, including the latter as part of it. This world of space is represented by science as a set of galaxies, star clusters, processes of transformation of one material state into another. And only the ability of an individual to assert himself under any conditions makes a human being a real beginning of human existence. It is potentially contained in the cosmic origin of man, but it is realized by him in the personal space between and non-existence.
