If the stars we see are light from millions of light years away and they see our Sun’s light the same, is the whole universe “existing” in the same time?

Question

Hi all, I didn’t know how to formulate the question in a non stupid way so I’ll explain.

If the light we see from stars in the sky are actually “the past” as they’ve left their source light years ago, from another point in the universe another planet sees our Sun’s light the same way, correct?

If that’s the case, if there was an “universal year” or an “Universe’s current year”, would all the stars and planets be living in the same year?

Maybe I am 5, I feel 5 right now.

Thanks 🙂

Mmm, in simpler terms

The light we see from the stars may be from the past, but seeing the said light is a form of observation.

I think you can state that all objects “exist” right now and that maybe there’s a universal concept of “time” as X arbitrary units away from a beginning point in time.

At this current point in time, stars and planets exist all at the same time X (assuming X is some billion something years from the big bang, if you believe that theory). The light that they emitted reaching our eyes can also be posited to exist as a photon (light particle) in a specific location in space and time.

Just… yeah, the observable universe is very human-bound, and while things exist, it may not necessarily be what you can observe.
