Suppose all these Creationists are right (sort of)

At the looney end of the literalist, creationist spectrum are the mind-numbed souls who insist that the Earth (and for all I know, the whole universe) is just a few thousand years old, and that some supernatural entity made our reality in the course of a few days (despite the logical problem that 'days' hadn't been invented yet).

I guess we've all seen self-important politicians making claims to have set things in motion, when in fact they just happened to be in the right place at the right time but being politicians they understood the advantage of claiming to be author of events rather than an opportunist seizing the moment.

Suppose then that what was created a few thousand years ago was the supernatural entity rather than our reality.  There is no good explanation for how consciousness exists in relation to the physical reality of our brain, so perhaps whatever is behind consciousness can give rise to other 'bigger' things.  Maybe a few thousand years ago something happened to humans to bring into being this supernatural entity - not just as a useful fiction in stories, but as some sort of thing that is greater than the individual humans it depends on. As this entity became more aware it realized in ever more detail the wonder and complexity of the reality into which it had arisen, and, with child-like arrogance, it assumed that if things existed it must be responsible (or at the very least claim responsibility).

So maybe the creationists are right.  'God' created the world in six days a few thousand years ago - unfortunately that creation was purely in its own mind, and the reality on which we depend had been around (and far more awesome) since time out of mind.
