Why are your ears at the side of your head and not in front where your eyes are?
Ears can detect sounds from all directions, and placement on opposite sides of the head helps to determine the direction of sound sources. The brain is able to process the different signals of the "stereo" sound.
Eyeballs of humans have a limited field of view -- about 120 degrees. Somewhere in time when humans evolved, for hunting it was more important to have depth perception (3-D) in the forward direction rather than peripheral vision needed to avoid predators. Compare the eye locations of owls with most other birds
Are you then suggesting that because humans are not predators, their eyes have a more constricted view than owls?
