HOW IS CREATION OF GOD DIFFERENT FROM CREATION OF MAN?

Man acts in parts whereas God acts in completeness, for example, man while constructing a building constructs first the plinths, then walls, then lintel et cetra. But God while making our bodies does not make, say, hands first, then legs, then stomach et cetra. He makes the whole body in one go. Initially that body is small and with the passage of time it grows bigger and bigger according to the laws of nature established by Him.
