I am neither theist nor atheist, but I do take issue with a 'creation', which leaves us with the age old problem of the origin of original material. The theists would have it that God created the world out of nothing at all. But the philosophers tell us only nothing can come from nothing, ie 'ex nihilo fit'. Now, cutting edge science (Lawrence Krauss) explains a 'universe from nothing'. But all of this assumes the world to be something real; something having material substance. But what if the 'material' stuff of the world is actually an illusion on a higher plane than your ordinary garden variety kind of illusion? In that case, it would solve two major problems: the origin of the original material from which the universe came, because there is none, and that there is nothing actually being 'created'. It is only a projection, a manifestation. So what is the nature of the 'material' universe then?: consciousness. Pure Consciousness.
The Big Bang was an event in consciousness, and consciousness is non-material, outside of time and space. IOW, it itself is No-thing-ness. Everything came out of Nothing.
The world, as we experience it, is a series of events in consciousness.
