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 🙂

No there is no standard universe time. Things happen when they are experienced or interacted with. We say the light left millions of years ago ….but did it? The only information we have is when the light arrived. We extrapolate backwards in time from our point of view but everything meaningful about that distant star is happening right now. It’s gravity it’s light all are “now” to us,

Unless we develop faster than light travel. Then there could be a universal time
