In the beginning, God simply spoke the whole world into existence.
Well, not quite.
Genesis 1 describes His actions during the six days of Creation as "God said... And it was so." All just a breath, and it came into being. But then in chapter 2, it gets more specific. "God formed the man of dust from the ground and breathed into his nostrils the breath of life." With the woman also, He took one of Adam's ribs and formed her from it. God didn't just breathe us into existence from a distance; He personally molded us from earth and blood. He got down and dirty to create us.
I think it's a beautiful reflection of what would come later, that to recreate us and to make us alive again, He'd again get down and dirty by taking human form and dying on a cross.
