When it comes to 'creator', the extreme ends of the pendulum are:
1.)creator is there and everything is possible including unstopable objects hitting imovable walls
2.)we live in an entirely mechanical world reducable to blind jiggling balls.
This too much assumptions about a being we know almost nothing about is the major problem. Fact is that the universe show some evidence of an intelligent creator. However, we see no evidence of an omnipotent, omniscient etc being. But since most people consider only the two options, they end up rejecting 'creator' all together because they find the idea of omnipotent being unteanable.
But is 'omnis' realy what drive us to desire God? Nope! All we need is a being with great potential. Not one that can 'do everything' cause we don't need most of those 'everythings'.
