    Depends what you mean and how you define each. If you consider that to be able to see something means that it has happened (optical trickery aside) then everything is in the past.

    If we are talking about celestial objects, definitely the past. Ancient history, in many cases.

    If we are talking about things in the same room, there is the latency of the light travelling across the room plus the latency of the whatever happens neurologically between the retina and the occipital cortex, combined for a few nanoseconds.

    Are you seeing something you don't believe???
