There and here at the same time .

[PLOTUS]

I would think the light with its images would be aged by the amount of time in years it took those images to travel to our eyesight and if it takes 2.5 Billion years for an image at that exact time to reach you, the next image could be of a White Dwarf Star because as the Star is 2.5 Billion years old, it could have past its life span. I always thought we were looking at the past.
Or,,,, I don't know!

Yes i get what your saying and it does take 2.5 billion years to get here , in our timeline . But for things travelling at the speed of light time stops as i understand it . So would not that particle of light not experiencing time be in its own timeline both here and there at the same time . And yes we are always seeing things things that happened in the past .

Imagine a train comming towards you the engine being the first photon to reach you, and then every other car behind the engine reaching you a moment in time later, etc. etc, and on and on as continuing parade of photons. it would be continuous events in sucession reaching you until the source stopped emitting photons and the last photon reached you.  Do you kind of folow me.  At least that would be my understanding of the sequence of events.
