The Big Bang theory of the origin of the universe tells us that, from a single point known as a singularity, the universe exploded into being. Not only did the ensuing energy coalesce into matter, but space expanded around it providing the room for energy to transform into matter.
Those original days were chaotic with the basic blocks of matter assembling themselves into atoms as the universe went from beach ball size to an ever-expanding vacuum pushing its boundaries further and further outward.
In the opening verses of Genesis, we are told that God created space and matter at the beginning of the universe. The writer did not use those words; indeed, the ancient writer would not have thought of creation in that way. The writer used the words available: heavens, to depict sky and space, and earth, to depict material or matter.
The key lies in the explanation that immediately follows the first declaration. After the statement that God created the heavens and the earth, we find that “the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.”
The writer wrote for his audience, the Hebrew people who had emerged from slavery in Egypt and wandered into the land now known as Palestine. As a distinct culture, they engaged in a rivalry with surrounding cultures as each claimed to be the best expression of humanity with their way of living superior to others.
Part of that rivalry lay in the myths (not fiction, but myth as origin stories) each culture adopted to explain the world in which they lived. An essential part of those myths was an explanation of how the world came to be, especially how humans arrived upon the scene.
Ancient peoples saw extra or super (meaning above) human power in the forces of nature, both local and global. While their immediate lives dealt with appeasing the hostile or arbitrary gods that they saw in nature, when they considered the origin of the earth and sky, they believed there were primeval forces that joined together to birth the world.
Tiamat, the female goddess of salt waters, mates with Anku, the god of fresh water. The chaotic nature of water and the uncontrollable storms they generate was embodied in these two. They mated (because in the Ancient Near East, almost everything was sexualized), children were the new gods who made war upon their parents, Tiamat and Anku, and succeeded them.
These ANE stories are also seen in the mythologies of Greece and Rome.
Then that one culture, the Hebrews, disagreed:
“In the beginning, God created the heavens and the earth. Now the earth was without form and empty, darkness was over the surface of the deep, and the Spirit of God was beating over the waters.”
Where did Tiamat and Anku come from? No one knows because creation mythologies always falter at the first cause: where did IT come from? There is no explanation.
The Bible declares that is unknowable: God has no cause, no origin, he is the great I AM. Always existing, always present, past and future included. (But that lies ahead of us.)
For now, we can notice the argument with surrounding cultures. God created everything, he was not born, he is not some unorganized force of nature.
In fact, what other cultures elevated into divinity, the swirling clouds of matter, the bouncing pings of energy, the expanding ball to make room for it all, the Hebrews snorted and said that their God did it all.
He made the world and it is his. There is no Tiamat, no Anku; that is only the chaos of newly-created matter and God made it.
In other words, the Hebrews were telling others: THAT’s your goddess/god? Our God made that.
The world is not the offspring of these original divinities. It was the single act of a single God.
In the immediate aftermath, everything was chaos. God had yet to organize it. The succeeding verses will explain how even as they maintain the theological argument.
“You worship that as god? Our God made that.”
Even in beginning, the Bible puts forth that the world was made by God. The Creator God has the privilege of ordering his creation as he will.
That brings in the organizing principle that I think unites the two Testaments, Old and New: the Kingdom of God.
