God

God as a symbol for spiritualism and nature etc. versus an omnipotent figure lurking above us.

if you rule out existence of a God, why is there anything and not nothing at all.

On the other hand, the existence of God cannot be quetsioned because that is temporal human definition.  Therefore, also, the possibility of creating the notion of God already proves His existence, for nothing that does not exist cannot possibiliy be comprehended or imagined.
