The Bible opens with a theopneumagensial statement of declaration unequivocally in Genesis. God explicitly states the number of days He spent to complete the cosmic design and the method He employed to create the cosmos, clearly stated in the Bible. Biblical theory is a substantiated explanation of the Word of God as established in the Bible to explain the world around us and the world beyond us (meta-world). It is a set of established biblical principles or laws to explain observable and non-observable phenomena, facts, or events on which Christians based their practice. Thus, the pneumagenesial theory is a biblical theory that sets out to explain the reality of the cosmos (the universe), its origin, and mudus oparandi. The theory states unambiguously that everything in existence has its own spiritual metaphysical determinant that controls it. The main thrust of this paper is to develop a theory known as pneumagenesial theory to unveil the origin of the universe through a biblical lens as opposed to the big bang theory’s claim. The methodology adopted in this paper is solus primus scriptura research (SPSR) to give sufficient evidence. The study also aims to debunk the wide spread lies orchestrated by big bang theorists and establish facts through a biblical lens that God is the Creator of the universe, as espoused by pneumagenesial theory in this paper.
