Everything you look at is in the past. Everything. The farther away the thing is, the farther back into its past you are seeing. On a global scale, this time differential is minimal, getting larger the farther out you go. The sun you see is from 8 minutes ago. The closest star we can see we are seeing what it was 4 years ago. No matter where you look, you are looking into the past and many of the stars you see are dead and have been for millennia.
