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?

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 🙂

Yes it exist at the same time but we don’t perceive it as so. Say you and a friend are on opposite sides of a pool and you jump in. The wave occurs as you jump in but across the pool your friend wouldn’t notice until it reaches them.
Light from the sun takes a little over 8minutes to reach us so when you look at the sun you see it as it was 8minutes ago.

If you really want to go down the rabbit hole you can look up an effect known as gravitational lensing which we can sometimes use to see different points of time due the the bending of light by gravitational forces.
