Answer:
I am mother and father, but never give birth or nurse. I'm rarely still, but I never wander. What am I?
I have cities with no people forests with no trees and oceans with no water.
I give people a huge fright but at the end I'm sweet. I normally celebrate at night when there's less heat.
I march before armies, a thousand salute me. My fall can bring victory, but no one would shoot me. What am I?
I run around the city but I never move.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
