When we look at a distant quasar we can visualize the history of the universe in its nascent phases.

But what about an observer at that point. The light from a quasar at the edge of the observable universe reaches us after say 13 billion years so we can say that that object was indeed present at that point in time. But what about the corollary? Our solar system is not older than 4.5 billion years (by a conservative estimate) so somebody looking at us from out there would opine that we don't exist. So how do we reconcile this?

 

Please advise.

 

Thanks in advance.

If we look at something that is 13 billion (or whatever) light years away, then we will see what existed at that time. If they look in our direction, they would not see our solar system, but they would see whatever existed here13 billion years ago (which probably includes our galaxy).
