@Mchuna,
The Image of God here is a representation of a nature of God known as The Trinity.God the Father, The Son, and The Holy Spirit exist in relationship one to another.
By creating Man in His Image,it shows the importance of male and female relating properly to be able to function fully as man.
Quote:
before he created Adam and eve,so was the first man both male and female?
This should perhaps highlight their closeness.
Are you asking if its possible for two persons to exist on one body.I would say ...Yes.
