I do NOT believe in creation ex nihilo, creation out of nothing.
The singularity from which the Big Bang exploded was some thing.
That singularity contained All-time, All-space, All-matter, All-consciousness, All-spirit matter, All-intelligence, All-light, All-truth, All-Law, All-potential, and everything else that became this universe.
That singularity was some thing, and that singularity contained EVERYTHING. That reality is the exact opposite of creation ex nihilo, which reality makes "creation out of nothing" a false concept or a false idea.
This is indirectly related to this discussion. It begs the question as to whether there is Something outside of this universe that can be fed into this universe, or whether God Himself was inside the singularity that became this universe.
