In this article, on the basis of a new methodology, we consider basic Ontological problem of the origin of existence of All that is (das Sein). Later, especially in this respect, we are trying to offer the new approach to prove and explain the (Higher) being and the God. This article is based on Meta – dialectical method and is a result of research of the meta-logic and represent an extension of the classical Dialectic methodology. It has been found that such redefinition of the dialectic methodology can be titled as a Dialectic Relationism which includes in itself the principles of the General System Theory. In an attempt to prove the existence of God, in the framework of new approach, it has been proven here to be suitable to use Non-axiomatic logical methods, in order to avoid the tautological “traps” or paradoxes. Relationism of dialectic orientation, better explains the natural and physical phenomena than the more generally defined Classical dialectic and other logic(s) and concepts based on the Classical axiomatic approach. The formulated dialectical relationism includes the new dialectical principles which are: 1. inseparability of the fundamental elements of the relation, and 2. the irreducibility of the fundamental relation containing the inseparable elements. Thus the basic relation becomes more fundamental category of the non-separable basic elements. Applying the relationism to the Ontology for resolving the most fundamental paradox or basic question “Why is there anything at all?“ we are able to provide an answer to that basic question. By applying the methodology of the reduction to the absurd (on the reformulated ontological question of “Why anything exist in relation to Nothingness?“ (oppositional dialectic form) ), we had derived to the conclusion that, “Nothingness” (as a pole opposite to “Everything”) is impossible per se (the poles / elements are inseparable i.e. Something always must exist, because the basic relation is irreducible and elements (Nothing, Everything) are inseparably linked. This is similar to the quantum physics where quantum interactions are irreducible. Cosequences for the theology are in fact that the most fundamental category is in the same time most general information and complex cattegory-entity, so that such order is in the framework of relationistic logic reducible to certain being with the identity and the subject as the most general cattegory-entity that is the fundament of the system.
