There is no reason to believe cause and effect hold always, in fact they don't.
there is no reason to believe a god is a satisfactory explanation for things we don't yet know.
in blaming god for causing the universe is the most simple minded excuse for anything.
then of course you have the job of explaining which god. oh lemme guess@you mean Allah.
God is just another word for ignorance and a longing for a big daddy in the sky to make all things you feel wronged about right.
