The OP question seems to be solely for folks who believe in the God of the Bible (either Jewish or Christian bible) or the Koran. It doesn't seem to fit very well for a pantheist, for instance. It certainly cannot even be answered by a person with my belief system. If there is a god or gods that created this universe, I don't think their motivation was your personal happiness. I don't think they think much more of you than you do of the microbes in squirrel intestines.
Anyway, if the Great Green Arkleseizure sneezed out the Universe, why are you not afraid of the Great Handkerchief?
