Bernardo saw what appeared to be the ghost of the late King Hamlet, the young Hamlet's father.  I say "appeared" because they cannot be certain it is really Hamlet's ghost, or a spirit pretending to be Hamlet.

Marcellus thinks Horatio should speak to the ghost because he is an educated scholar and may be able to discern whose ghost it is as well as what its purpose is on this earth.
