This comes from stage directions, which were brief - probably because they were originally copied out by hand and people wanted to save effort and paper:
Enter Hamlet
Enter Bob, stage left
It's a direction in a play to say that a character comes onto the stage. It is used idiomatically and metaphorically to talk about something entering the discussion, with the stage being conceptual and metaphorical.
