Keep your pity and your inability to answer the question of what, other than chemistry and physics in your brain, allows you to reason?
I did answer it! What are you even talking about? I've proven that you cannot even ask the question without presupposing that MY worldview is true! The very fact that you are here is PROOF that you are wrong!
Further, reason is not just another biological function, like digestion or respiration. Digestion and respiration are purely physical processes, while reasoning involves
meaning, logic, and truth. These cannot be reduced to chemistry or physics. If truth exists, it must be grounded in something beyond nature.
The consequences of this argument are clear. Naturalism cannot explain reason. Any attempt to do so either undermines itself or reduces thought to a meaningless byproduct of physics. However, reason
does exist, and we rely on it every day. The only explanation that makes sense is that reason comes from something beyond nature, something rational, something personal, something that can be described as God.
If you presented evidence before I missed it so just do it again.
You didn't miss it! You cannot have missed it. You may not have understood it or you may have ignored it, but that isn't the same thing.
