However if I may briefly state: God as Creator is just that, He is presently creating. It is not possible (in the Catholic religion) to believe God is some omnipotent "watchmaker" who at one time created everything and now sits back and watches with casual bemusement. Indeed, this would make Him out to be quite cruel indeed.
We believe He is constantly creating today, for many reasons but one among them is precisely because of the problem of evil. We believe He constantly creates so as to always bring out greater good from evil, this defeating it at every turn.
Again, that's a very brief treatment of the subject. The work by C.S. Lewis I mentioned earlier is very helpful in this regard. I shall keep you in prayer as you struggle with this issue.
