Those first disciples really had no clue. In the other Gospel accounts, in Mark's especially, the disciples come to the tomb and after they discover that the body is gone (it's women disciples that do this) they're all upset and they just leave without saying anything to anybody. They don't know what to do. Today we hear about Mary Magdalene coming to the tomb and being upset. At least she runs and gets Peter and John and they come back to see what's going on, but they too leave. Nothing seems to change.
