can have seen

Hi,

You can´t have seen the Jacobs yesterday - they´re in Australia.

Why there is present form of the word "can"? Thanks for your reply.

The speaker is relating the statement to the present utterance of the listener ( 'I saw them yesterday' ). In spoken English, this is fine and common; in written English, the writer would probably reconsider and change it to couldn't . It is an odd formation, really, isn't it?

It is. And according to what you wrote even more because this sentence is included in the entrance university exam.
