And yes we are always seeing things things that happened in the past .
the way i see it is,time stop for every proton. as it moves through space, until it gets to us. then the next one does the same.
so as soon as it reach it's top velocity (which is instant) time for it stops as it moves through space, it's starting point is it's past, then when it reaches us is it's present, then beyond us it's future.
here maybe these two videos will help you understand what i'm trying to say.
