And when I was little I believed that the Moon was really the Earth and there no Moon at all. My mom then confronted me with this question: if that is the Earth, and there is no moon, what are we standing on? I patiently explained to her that there is a huge ziplock baggy hanging from the moon with dirt in it -- and that is what we were standing on.
