Then the LORD God said, "It is not good that the man should be alone; I will make him a helper as his partner." So out of the ground the LORD God formed every animal of the field and every bird of the air, and brought them to the man to see what he would call them; and whatever the man called every living creature, that was its name. The man gave names to all the cattle, and to the birds of the air, and to every animal of the field; but for the man there was not found a helper as his partner. So the LORD God caused a deep sleep to fall upon the man, and he slept; then he took one of his ribs and closed up its place with flesh. And the rib that the LORD God had taken from the man he made into a woman and brought her to the man. Then the man said, "This at last is bone from my bones and flesh from my flesh; this one shall be called Woman, for out of the Man this one was taken." Therefore a man shall leave his father and his mother and clings to his wife and they become one flesh. - Genesis 2:18-24Why the "name game"? Did God not know that Adam would not find a partner among the animals? It seems that the name game could have been cut out of the story with not much affect to the intent.
The point of the name game is not because God didn't know who Adam should have as his partner, the point was to vividly demonstrate to Adam the goodness and kindness of God to design a perfect partner for him, and him for her.
Why didn't God just make another man and given them both the ability to asexually reproduced? Because that wasn't the perfect partner that Man should have.
The last verse of the passage explains the reason for marriage:
(1) I wasn't good for Man to be alone,
(2) God (and Adam) had many options to choose from for a partner,
(3) God demonstrated that he designed the perfect partner for Man: Woman
I don't see any other way to interpret this passage with integrity of heart as a Christian, and come to the conclusion that Man is also the perfect partner for Man, or Woman the perfect partner for Woman. If we attempt to draw this conclusion it is reminiscent of account immediately following...
"[the serpent] said to the woman, "Did God say, ..."... Yes, he did.
