Which human sense provides the most information about the external world first?

The sense that provides the most information about the external world first is sight. This is because vision allows humans to take in a broad spectrum of information and stimuli almost instantaneously. Our eyes can detect light and color, enabling us to perceive our surroundings, recognize objects, assess distances, and respond to changes in the environment rapidly.

When it comes to survival and navigation, sight plays a critical role. For example, being able to see potential hazards or opportunities in our environment allows for quick decision-making and responses. While hearing, touch, and taste are important senses that contribute to our understanding of the world, they typically provide information that is more contextual or detailed rather than the immediate broad overview that vision offers. Therefore, sight is generally considered the primary sense through which we assess and interact with our environment first.
