Answer:
What is lighter than what it is made of?
I am always hungry, I must always be fed. The finger I lick will soon turn red.
I am the hole in the night, the ever watchful eye. I return in a cycle, to enlighten the sky.
I am a fire's best friend. When fat, my body fills with wind. When pushed to thin, through my nose I blow. Then you can watch the embers glow.
Halo of water, tongue of wood. Skin of stone, long I've stood. My fingers short reach to the sky. Inside my heart men live and die.
I march before armies a thousand salute me. My fall can bring victory but no one would shoot me. The wind is my lover one-legged am I. Name me and see me at home in the sky.
