@ Sandy - Yes, its called the "God of the Gaps" concept, whereby any gaps in current scientific knowledge are claimed by the religious to be proof positive of gods existence - and the big bang is no different in this regard.Nor is it a new concept - its been offered before as proof of god, but of course it is no such thing.
Its true to say that we dont yet know what happened in those first milliseconds of the inflation/expansion, so its possible ( but highly improbable) that some supernatural being was around to "roll the dice" - but the gaps where a god might conceivably reside are getting smaller and smaller with each advance in our scientific knowledge, and claiming those gaps as the place where god resides just means that this allegedly omniscient being is remorsely reduced to a shadow, a pale, ineffectual pastiche of the god as represented in the bible. Is that what you want?
