The difference between Present Perfect and Past Simple is often subtle but crucial.
Past Simple
Use Past Simple for actions that finished at a specific time in the past.
- I visited London last year. (It's done, and we know when)
Present Perfect
Use Present Perfect for actions that happened at an unspecified time or have a connection to the present.
- I have visited London. (Experience matters, not when)
- I have lost my keys. (I still don't have them now)
