I know I'm not the only one to ponder this(obviously). How did that cow jump over the moon? Could it fly? Of course not. The song, after all, does not say "and the cow flew over the moon," now does it? That also leaves out the possibilities of a rocket ship, jetpack, levitation, and telekinesis. Did he use a trampoline, perhaps a giant pogo stick? Now that's just silly. A trampoline could never launch someone that high, nor could a pogo stick. What options does that leave us? Was it a miracle of God? Unlikely. Why would God waste a miracle on a jumping cow? I've thought about this subject, and I believe I have an answer.
If you take into account there is no true "up" in space, I could, technically, be over the moon right now. While the moon is over me and Earth below, this would not be true were I on the moon. Were I on the moon, the moon would then be below me and Earth over me. As Earth would now be over me, so would all the people on Earth. Therefore, as I am on Earth, were I to jump, I could technically be jumping "over" the moon. The term "over" is all a matter of perception, and is not defined in the poem/song as to whose perception it is, nor where that person is at the time.
