Folks really do understand that we won’t be looking “ back in time”, just “in the distance”, right?

Considering the speed of light, the light we are seeing is very old.

It takes a year for a light to travel a light year.

Uh huh.
Agreed. But we are looking back in time, just at light emitted by an object far away.
A review of how the speed of light is derived is an interesting convention. An agreed upon working solution. In fact, some learned folks actually admit that the speed of light and an image are not very closely related.
Working science, not absolute science. Pretty standard.
