Perception is, of course, critical. We perceive a finite universe and a finite past.
Even in the distant things we perceive things could vary materially. In every direction, the things furthest away are also moving fastest which could suggest a variety of things. We could be near the center and moving slowly relative to the center. Things might be collapsing toward the center and we a part of the collapse. Things might collapsing toward the center and we are on the fringe, either expanding or collapsing. It could be an illusion caused by factors that are not well understood. Cosmology is complicated.
I will restrict myself to the galaxy. Even the local cluster is too far away at sublight speeds. Not so our galaxy. A single megayear and we would span it all.
