The spiritual war is the reason the world is how it is, with so much pain and suffering, confusion, selfishness and darkness; and so many events in our world (car crashes, etc.) happen because of this raging war. The unsaved have no clue about this war, but if they were alert (Col. 4:2) they would see the signals all around. Instead, they are blindly believing crazy philosophies like cause and effect, or "things happen all by chance" as the cause of things. That's just satanic information from the kingdom of the Devil (the world, 2 Cor. 4:4).
