I was just wondering that We see objects thru our eyes and light has to reach our eyes so that our brain can process that light.

But then there must be a time difference between that object which I see and me, as light has to travel from that object to me, let us assume the difference is in milliseconds.

Does that mean that every object I see, is past in time?

Yes, ofcourse the sun we see is nearly 8.30 minutes old(which is very far from us). Though objects near you say 1m apart are $t=1/3*10^{-8}$ seconds old, (roughly a nanosecond).The stars you see (the light coming from them ) which are billions light years away are the past . Who knows maybe they are not even there now?
