Because the light itself
is information about what is out there in the direction we are looking. If only blue light is arriving from one point in our visual field while only green light is arriving from a point just to the left, then this tells us that in the direction we are looking there is something green just to the left of something blue. This doesn't require light to carry or bring images or anything other than itself.

Apart from the fact that this is nonsensical, it is also completely irrelevant to the discussion. You are talking about what happens with light beyond the point at which we can see the object, so this has no bearing on what happens when we are looking at and seeing an object. In that case light is hitting the object, and the nonabsorbed light is bouncing off and traveling to the retina
in your explanation as well as in ours.
