This is not quite as crazy as it might seem at first glance. In physics, there are many theories suggesting that our Big-Bang is just one of many [ including my own theory ]. We are forever excluded from information outside our B-B, but that does not prevent us producing models that would work within our understanding and observation. Similarly, we will probably be prevented from reaching the true creator, and will need to be content with dealing with his intermediary.
Disclaimer: This is NOT a lead in to my unpublished short work - "The Bath-Tub of Creation". However, if pushed, I could provide a synopsis [grin].
