Peacemaker, I believe the answer may be that women know things because they sense or feel that they are happening (that means even if they see something, it is seen as a feeling), as opposed to men who see things by seeing them happen.
If you have a mother or have been married for at least five minutes, you will know what I’m talking about!
Therefore ‘Witnessing’ has to be based purely on vision without any feelings or emotion or sensing.
