"While the actual phrase 'out of nothing' does not appear in the Bible, this hypothetical method of creation was proposed by Creationists from the following passages in scripture:
Gn. 1:1 'In the beginning, God created the heavens and earth'
Psalms 33:6 By the LORD's decree the heavens were made; by a mere word from his mouth all the stars in the sky were created.
John 1:3 All things were created by him, and apart from him not one thing was created that has been created.
Rom. 4:17 .... - the God who makes the dead alive and summons the things that do not yet exist as though they already do.
Heb. 11:3 By faith we understand that the worlds were set in order at God's command, so that the visible has its origin in the invisible.
While it is clear from the above passages that God created all things, it is not defined at all how the creation took place. The closest of these to defining a process is Ps 139: 'by a mere word from his mouth all the stars in the sky were created.'. That obviously was quite a word since the stars come in different masses, nuclear varieties, and position throughout spacetime. Add to this the mystery of how the sound waves traveled throughout spacetime without air to transmit the pressure waves and you have a real conundrum. I hope you can recognize from yet another metaphorical expression, that this passage does not express how it really came into existance . Be that as it may, it did not just pop into existance 'ex nihilo', but was carefully and thoughtfully brought into existance by some form of communication of information by God himself with direct causation from God being the point of the metaphor.
There is no reason to set aside the laws of physics that God created at that point in time by His communication and claim everything came from nothing. Everything came from God's communication of the details of the universe on Day 1. Day2 and on followed from the initial communication, the established physical laws, and God's preplanned interactions with the universe thereafter.
To me, 'ex nihilo' seems to be a concept that the atheist quantum physicists want to get us to buy into to put God out of a job. If they can convince the world's inhabitants that quantum uncertainty can pop things into existance out of nothing from borrowed energy, then anything can pop into existance given enough time, space, and other dimensions including new universes and multiverses. These people have a love affair with an infinity without God. According to their thinking, the conservation of energy and information get thrown out on the universal scale and chaotic eternal inflation becomes the new creation tool, not God.
It seems to me that we should jointly fight this concept: random chance creating universes and their laws. Please read up on Dr. Andre Linde and his eternal inflation theories that many a physicist believe.
I am opposed to the idea that God 'speaks' animals and plants into existance for two reasons as I have often posted. 1) there aren't any passages of the Bible that infer or state that happening and 2) animals and plants couldn't survive creation this way unless the fixed physical laws were totally abandoned.
This creation methodology violates God's promise in Je 33:25 that the physical laws are dependable and not changing.
