belief in God is an innate inclination and conception of reality

The argument that belief in God is an innate inclination and conception of reality that is not derived from the natural world:

P1) If meaning can only be derived from the natural world, then all conceptions of reality are derived from the natural world.
P2) If all conceptions of reality are derived from the natural world, then they must be a coherence of meaningful experiences.
P3) People believe that there is a meaningful transcendent reality (i.e. God) that shares no properties with the natural world.
P4) If P1 and P2, then P3 is a conception of reality derived from the natural world, the content of which is a coherence of meaningful experiences.
P5) No number of meaningful experiences can direct one to consider the possibility of something meaningful beyond said experiences.
P6) Therefore, P3 is not a conception of reality derived from the natural world.
