Our sight does not “see” any distance whatsoever. Anything we see is because the the light has come to our eyes. Same applies to cameras.

In other words, our eyes are severely limited as to what they see because they rely on light either being emitted by a distant object or light being reflected off a distant object and arriving at at our eyeballs.

We don’t see “away”. The “away” comes to us.

We definitely can NOT see everything else in the universe. There is an unknown amount of the universe that we will never see because of the expansion of the universe being faster than the speed of light in some areas. In the far future, less of the universe will be visible due to expansion. We are lucky that we can see as much as we can.
