In the vastness of the universe, with galaxies swirling through space, the book begins with simple words printed on the darkness. Moving closer to our world, we see the solar system, our sun at the center. Closer still, we see the huge ball of fire, the sun, and the third planet out from it -- our blue Earth. From Earth looming huge on the page, young readers view smaller and smaller things, from mountain to tree to man to child to kitten to mouse to flea to microscopic beings, amazing in their complexity.
