Mars & God

At lunch today, Gabe asked, "what is holding Mars?"  Turns out, Gabe was asking about the universe and gravity.  He wanted to know how Mars stays up in the sky.  When I told him that I didn't really know the answer to that (thinking that 4.5 is too young for a gravity explanation) and that we could talk to Daddy (sorry, Jay) about it later tonight, Gabe suggested that we ask God.  As, according to Gabe, "God knows everything."
