I like an explanation I heard a rather long time ago about the creation of the universe and the answer to theists question "Why is there something rather than nothing".  Zero is very difficult to maintain, and so reality fluctuates between the negative and positive.  I have no idea if this could be so, but it seems poetically simple. Nothing has a very hard time existing, so to speak.  I imagine an endless abyss with 1 and -1 where as you slip down the walls of the canyon you get to .01 and -.01 and deeper still .001 and -.001, the decimal slipping back again and again endlessly... never reaching exact zero.  However that's how I imagine it, you can obviously see I'm no scientist.. just a dreamer that seeks more than the bankrupt theisms can give.
