Why did God create man? Genesis 2:7 KJV reads,


  And the LORD God formed man of the dust of the ground, and breathed
  into his nostrils the breath of life; and man became a living soul.


Why do this?

There must be a very good reason. I read the Bible but don't know it well enough make anything out of this main premise (man). 

Any supporting references are helpful (articles, Bible references, etc.)

P.S. Please do not confuse with: Why did God create such complexity in man?
From the Westminister Shorter Catechism Question 1:


  Man's chief end is to glorify God, and to enjoy him for ever.
