Just for the sake of argument, if there is a creator, the placement of the human species on this planet may be just an experiment, one that, I think, may be failing.  The problem is, the only real constraint, is the carrying capacity of the whole planet, a basic design flaw.  When we get overpopulation of, say, elk, we can bring in the wolves or bring in the hunters.  The only thing that is going to stop us is virtual destruction of the planet's ability to support us.
