Hi Cofty,
As soon as the person posing the question carefully defines what they mean by "god" we can prove beyond all reasonable doubt that it does not exist.
How about this: An entity that has started a simulation which we know as the universe which is in its n'th iteration for whatever purpose this entity has desired e.g. experimentation with universal parameters/sadism/personal pleasure etc. This entity is all powerful/impersonal and does not care about individual sentient outcomes but only the simulation outcome.
