That strongly depends on your reference frame. As in, what system are you looking at? Where are you drawing your box? If your box is around the entire universe, then yes, every action is a reaction stemming from the big bang, with very few notable exceptions pertaining to black holes that I wont go into.

However, if your reference frame is a hand and a ball, then the hand pushing the ball is an original action, the ball moving its reaction.
