“How does that contradict my post?”
I may have missed your point. Scripture is vague on what?
Scripture is too vague concerning the creation to form hard opinions. The bible is not a science book. The user guide for my leafblower is longer and more detailed that the biblical creation account.
In a manner suitable for a primitive people to understand, God took credit for having created everything. Exactly God created all things he didn't tell because there aren't enough trees on the planet to produce the paper on which to write such design specification. Again, the bible isn't a science book.
Without understanding how he did it; classical evolution or intelligent design, we can give all credit to God. Once we begin speculating as to how God might have gone about his creation, any engineer/architect would tell you, the greater feat of design would have been to create all laws of the universe from which everything followed at the moment of creation ie "big bang"... the instant something emerged from nothing.
Also valid for speculation is that God periodically intervened to guide his creation in the form of intelligent design. This need not diminish the greatness of his creation. Perhaps he had to intervene because some other being kept interfering with his creation. Who knows? We can only speculate because the bible doesn't say.
