[You leave at precisely 12:00:00 pm and travel for 1 light second away from me. I observe you the entire journey because air is not opaque and the light passing through air is invisible and has no spectral content to be visible observed / i.e space is ''gin-clear''.] You will view me at the destination in two seconds. One second to get there and one second for my image to go back to you. You do not see through space at all. You have no idea how your vision works. Your under the impression light is infinite. If light were infinite we could not distinguish images. We would see everything at once and view nothing.
If you stood 1 light second away from me in absolute dark, and synchronised we both release a single photon directed at our eyes , we would both receive the opposite photon at the same time.

Yes we would receive the photon physically synchronized with the present. But I moved physically in that one second time light took to reach you and you did not see my movement of the new event position vs. where the photon was originally released. You view my position where I was a second ago not where I physically exist in space present.
