The eye can see 12 miles unobstructed in an atmosphere. This is because the atmosphere diffracts and diffuses the light that passes through it. The more atmosphere light passes through, the more it’s scattered.
The sun is 93 million miles away, and other stars even further away, yet we can see them because there’s no air in between them and us beyond our own atmosphere, which isn’t thick enough to completely absorb or diffuse the light.
Human eyes are not restricted to 12 miles, they can see as far as light can travel to them.
