"Out" is used here as a preposition to indicate that they went away from home to do some activity. In this case, it specifically refers to being outside. However, it can usually be used to express that someone is doing an activity outside the place where there home is or where they originally were. Ex: What time are you going out tonight? Ex: We went out to see if we could find the cat.
