the Atheist, because when a baby is born, or a beautiful sunset appears, or a loved one returns from war, or science declares the size of the universe, they have no one to thank?
Its much more amazing when something happens then when someone does it, so no, you shouldn't pity us. Art might be beautiful, for example, and you can then thank the artist, but the natural beauty of the natural world makes art made by man seem pale by comparison.
