We do not use the present perfect with expressions that refer to a completely finished period of time, like yesterday, last week, when, then, five years ago, in 1995. The simple past is used with this meaning.
- I saw Alice yesterday. (NOT I have seen Alice yesterday.)
- I was born in 1979.
- She died three years ago.
- John left ten minutes ago.
In American English, the simple past is often used to give news.
- Did you hear? France declared/has declared war on Britain.
- (GB Have you heard? France has declared war on Britain.)
- Lucy just called. (GB Lucy has just called.)
- Honey, I lost/ have lost the keys. (GB Honey, I have lost the keys.)
this is the first time etc.
We use a present perfect tense in sentences constructed with this/it/that is the first/second/third/only/best/worst/etc.
- This is the fifth time you have asked me the same question.
- It is one of the most interesting books I have ever read.
- This is the first time I have heard her sing.
