What is the likeness of a human being?
Likeness is generally used to mean "similar to, looks like,
appears to be" - paraphrasing the Bible 'made in the likeness of
God.' Here it may refer to the fact of having free will, but it
appears even more that it means we are built to create: creativity
is the spark we've gotten from God that no animal so far has shown.
In this way we are 'like' our creator. It can also relate to a
painting or drawing of a human.
