Where did matter come from?
Where did it's properties come from?
Where did order and complexity come from?
There are scientific (non-deific) theories that address all of those questions.
There is also what the bulk of Christians who understand science believe: God sits OUTSIDE the Universe. His omniscience is so far beyond our understanding that creation of a Universe with an entire set of working laws that we are barely getting the inlkling of fathoming.
But as designed and implemented, the Laws don't NEED Divine Intervention.
