Does Genesis's creation account depict creation “ex nihilo”?

Any answer to the OP that presumes that God created something apart from or outside of himself, says that there is something bigger than God... a place that contains God and his creation. But since there is nothing bigger than God, and the heavens cannot contain him , he created the universe within himself.

As the sages say, he created the void within himself in order to make room for us. Then he spoke into the void to create everything else.

This is ex-nihilo.
