Anything you see right now is a past event. It is just that for most human day to day activity, light travels so fast that this "past" is a very very small bit of time.
If someone stands 10 meters away from you and throws a ball, you would only see (from your perspective) the ball leaving their hand 1/30000000 of a second after they (from the thrower's perspective) throw the ball.
The further the distance, the longer the time difference between when you see it and when the event happens.
