The atmosphere is a peculiar thing. There can be different things in the air and we wouldn't even know it. We inhale different things from the atmosphere and we sometimes don't even notice.
Energy is in everything. We have energy, a pencil has energy, heck! A piece of cheese string has energy. When we move, we are using our energy, when a pencil writes or falls, that is energy. When we eat cheese, it turns to energy in our stomachs!
