The question of "why religion exists and the epistemic value of religious beliefs" is among the most significant contemporary theological issues. Theories proposed in this regard can be divided into natural and supernatural explanations. Among the natural explanations is the "God gene" theory by Haimar, which can serve as a basis for naturalism and religious non-realism. In contrast, the "innate religiosity of humans" provides a supernatural and realistic explanation of religion. From a naturalistic perspective, however, innate religiosity is reduced to genetic foundations, and in this case, it does not imply supernatural truths, including the existence of God. Given the importance of this issue and its role in the foundational bases of religious belief, this article aims to examine Haimar's perspective and its theological implications, as well as its relationship with the theory of innate religiosity. The research method is library-based for data collection and rational-analytical for judgment. The research finding is that, contrary to the expectations of naturalists, Haimar's genetic perspective does not have reductionist or antagonistic implications toward religious realism. Instead, alongside innate religiosity, it can contribute to a two-level explanation of human religiosity. Nevertheless, the "theory of innate religiosity" carries more significant theological implications, to which Haimar's genetic perspective remains neutral.
