Things that make you go "hmm."

Over the course of the last two days, I have started and finished reading "The Shack." Without giving away any important storyline information, in case you intend to read it, I must admit that this book made me ponder what I would do if put in the situation of meeting God in person. What questions would I ask?
A boy I dated briefly in high school introduced me to the music of Chris Rice. I have since been a fan because he (or at least his songwriter) shares in my interest of absurd thoughts. The first song of Chris' that I heard was "Questions for Heaven." In this little ditty, he asks God such questions as: Do you ever play tricks on the angels? What causes deja vu? Do our jokes make you laugh? What's your favorite cartoon? Oh, and what causes deja vu?
In addition to all of the deep "Why" questions I could create, here are some of the less important, but equally fascinating things I might ask:
*When a person steps into snow, creating a footprint, why does that footprint disappear as more snow accumulates? Shouldn't the snow build equally on the ground surrounding the footprint as it does the footprint itself? If that was the case, the snow would get deeper, but the footprint would still be visible.
*Is the air that is on Earth today the same air that has always been on Earth? If yes, the air we are currently breathing is the same air that was, at one time, breathed by our ancestors, dinosaurs, and Adam & Eve. If no, how long is the shelf-life of air? At what point is pulled from the rotation?*Speaking of Adam & Eve--I understand that all of the struggles of life to which we are subjected are because of the choices they made. But I don't understand why the first people created had to be such idiots.
*How do wireless electronics work? I have a hard enough time trying to understand how my voice travels long distances via land-line telephones, but c'mon, mobile phones?! I speak into a phone, the words somehow get trapped in this little device and then are teleported to the device of to whomever I am speaking? It makes no sense.
*I can only assume that when we humans get songs stuck in our heads, there is some underlying message in the lyrics that you are wanting us to understand. So, tell me, what grand truth am I supposed to get from Zombie, by The Cranberries?
If you have any additional thoughts or questions you would like me to ask in the event that I meet God before you do, feel free to send them to me.
Until tomorrow.
