Since it "rises" everyday. It provides us with light and warmth and also it WILL die in approximatly 4.5 billion years. Does that mean the SUN is alive?
the sun doesn't really rise everyday, you know. It's the rotation of the earth that makes us it feel it rises!
And about dieng, it's like giving off it's fuel and becoming smaller..that's all.
By alive, if you mean breathing...it isn't alive!
