I'm not exactly sure what this great insight of yours is supposed to be. That our senses have developed ways to model external reality in our minds? This is not exactly news! Generations of philosophers have been pondering it.

Are you shocked, shocked I tell you, that our nervous systems have this ability? How could they not? We have to live in the real world, after all. We have to find water, food, shelter, and mates, avoid predators and hazardous environments, and generally get along. Evolution has been fine-tuning those senses for a billion years. Any organisms that did a poor job of "remote sensing" left no descendants.
