Of course, we have machines that can process various portions of the light spectrum, but are they capturing everything? Science theorizes too about ‘dark matter’ that we cannot see but that exists. Are there more things to see than light alone would reveal to us?
For example, sound and smell are senses that enable us to understand more of the world around us as well. They help us to ‘see’ a more complete picture, more than we would understand with sight alone.
From an evolutionary perspective, the chances of the human eye developing and evolving are truly small. From a scientific perspective, we know that animals have senses or abilities we do not, such as echolocation, homing abilities, far superior smell abilities, and the ability to see light that we do not.
