Northern Light part two

Ok. So the Northern Light were beautiful last night. But why did God make them? I know that the. Northern Lights are like atoms colliding and stuff with solar winds, but why did God make Northern Lights? Maybe He wants to show us how powerful He is. That He made that. Or maybe the world needed a covenant and the Northern Lights were like that promise. Like the rainbow shows His promise to Noah that He will never flood the entire earth again. I'll ask my teacher what she thinks. This is something to think about. What is the point of the Northern Lights?
