Gen 2:18-24 (ESV) Then the Lord God said, “It is not good that the man should be alone; I will make him a helper fit for him.” So out of the ground the Lord God formed every beast of the field and every bird of the heavens 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 livestock and to the birds of the heavens and to every beast of the field. But for Adam there was not found a helper fit for him. So the Lord God caused a deep sleep to fall upon the man, and while he slept 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 of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man.”
Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.
"It is not good that man should be alone." Those words spoken by the Creator are incredibly insightful. Leaving aside the biological point that man could not exist without woman, I find it evident that man would be incomplete without woman. And while it's true that life would be simpler without women (OK, a LOT simpler), it wouldn't really be life, now would it? So, every man should thank God that He had the wisdom to create woman.
