Time is relative and inexorably tied to space. What we think of as the speed of light is the speed of causality. What is now for you is not now for Alpha Centauri. They see us in the past as we see them in the past and Tau Ceti sees us both in the past. Yet we are all in the now. All these things are true.
I’d say that none of it is in the now, because it all involves distance and time. All those “nows” are different yes but also the “now” at the tip of my nose is different than the “now” inside my eye, is different than the “now” in different parts of my brain. And all of those are different than the “now” that I believe myself to be experiencing. And all of these things are in the past.
