I think a better a way to frame this to avoid getting hung up on the quantum mechanic thing is asking if a theoretical astronomer on a distant planet viewed the earth and could see its surface, what would they see. (Ignoring the kind of telescope you would need to even do that but this is theoretical fun so whatever!) If they were 100 light years away, would they be looking at earth 100 years ago.

I think your question is more about, that than anything else? Could be wrong.
