Many Indo-European languages have native speakers who have difficulty understanding the perfect tenses in English. Among other languages, the present perfect is most frequently used to express past time in French, German, Latin, and Spanish, among others. In English, this is not the case. The simple past is most frequently used in this context as the proper tense for past time. The present perfect has a variety of meanings in English, but it cannot be used to refer to events that occurred in the past.
Based on my knowledge of the other Indo-European languages, I believe that English uses the past perfect in the same way that they do: the past perfect is used to indicate a past action that occurred before another previous action. In English, on the other hand, the past perfect is not required if other words such as "before" or "after" clearly indicate the sequence.
