No matter your spiritual beliefs, if you hold any, the answer is the same: sometimes, why is not knowable. If you open the refrigerator door and a tub of Kozy Shack tapioca pudding tumbles out and splats open onto the floor, you clean it. You don’t stand there and question why it happened, how it was possible. Why doesn’t matter now.
