Interesting question... we are discussing an omnipotent eternal being and we want to set the parameters that define the proof of his existence. Could it be that our scientific method and our logical rational methodology are so inadequate when faced with dealing with the very idea of our creator. I think we should challenge our beliefs on what constitutes proof when dealing with the idea of explaining the "all". Our five senses and cognitive abilities must be so inadequate.
Worms in the wood concieving eternity....
