Consider an ordinary ant. To an ant, a dog looks very big. Then consider a germ found on the ant. To the germ, the ant looks very big. Now, think about the dog again. To a dog, a human bean look very big. And if you're a human, an elephant looks very big. And if you're an elepahnt, a dinosore looks very big (for the moment,_ just ignore the fact that dinosores don't exist). To a dinosore, the world looks huge. To the world, the universe looks very big.
Except for a germ, everything in this world of ours has something that is smaller than itself. And, except for the universe, everything in this world has something that is larger than itself. When you think about things from this perspective, "size" takes on a hole new meaning. As Albert Einstien says, "it's all relative!".
