The Waters that Changed Genesis: “Let there be an expanse between the waters…”
What in the beginning was a vertical act of ordering – the Spirit of God above the waters – was transformed, through a small interpolation, into a mythological architecture of the world: two seas, a dome between them, and “waters above” ready to be poured out.
This modification did not appear from nowhere. It was introduced in order to make room for the flood.
Genesis was rewritten to support a story that did not belong to it.
A Vertical Order, Not a Layered World
The original text of Genesis begins with a simple and profound image:
“In the beginning God made the heavens and the earth. The earth was formless and empty, darkness was over the face of the waters, and the Spirit of God was moving over the face of the waters.” (Gen 1:1–2)
This is a perfectly vertical structure. God is above, matter below. Between them there is a difference of nature, not a conflict. The waters are “the deep” (tehom) – the undifferentiated mass of the world, not a being, not a goddess, not a cosmic adversary. The Spirit does not fight with chaos; He dominates it by His presence.
Everything that follows in the first verses is ordering, not separating. Light, dry land, sky, life – all appear through speaking, not through cutting. “God said” is the form of creation.
In this vision, there are no two seas, no spheres, no gates of heaven. There is only the “above” of the Spirit and the “below” of the waters, over which order is stretched.
The Intruder: “Let there be an expanse between the waters…”
This coherence breaks abruptly in verses 6–7:
“And God said, Let there be an expanse between the waters, to separate the waters from the waters. And God made the expanse and separated the waters which were under the expanse from the waters which were above the expanse.”
This is a sentence foreign to its context.
If the Spirit was already above the waters, what is the point of “separating” the waters in order to create an “above” and a “below”?
The “expanse” is no longer the tent stretched over the waters, but a wall between two seas. The text shifts from vertical to horizontal.
Through this single detail, Genesis adopts the mythological structure of the Babylonian world: a dome between the lower and upper waters. Instead of a God who stretches out the heavens over creation, there appears an architect who builds the ceiling of the world.
But why would anyone have made this modification? Why would Genesis need “waters above”?
The Flood – the Reason for the Falsification
The answer lies later, in Genesis 7.
There, the flood myth demands a physical mechanism by which the “waters above” can be poured out:
“On that day all the springs of the great deep were broken up, and the windows of heaven were opened.” (Gen 7:11)
For this scene to make sense, the world had to have already been constructed with two seas – one above, one below.
Thus arose the need for the “separation of the waters” in Genesis 1.
Without the “waters above,” the flood has nowhere to come from.
But since the flood was introduced later, as an adaptation of Mesopotamian myths of the Atrahasis and Gilgamesh type, the editors of the text were forced to modify the beginning of the world as well, in order to create the necessary framework.
The result is an inconsistency: a God who, after already being above the waters, “creates” the above once again by a separation between waters.
Here the “foreign hand” becomes visible – not one that falsifies brutally, but one that harmonizes mythologically. Genesis 1 was adjusted in order to make room for a later story. The flood changed creation.
From Spirit Above to Reservoir of Waters
Once the idea of “waters above” was introduced, the entire language of heaven changed.
The Hebrew term rāqîaʿ – meaning “expanse,” “spread-out covering,” “beaten-out surface” – began to be understood as a solid dome.
The Greek translation from the 3rd century BCE, produced in Alexandria, fixed this confusion through the term stereōma, “firmness” or “firmament.”
At that moment, heaven became a structure: a barrier between “waters above” and “waters below.”
This vision was perfectly compatible with Hellenistic cosmology and Babylonian myths, but completely foreign to the theology of Moses.
Thus, “the expanse of heaven” – a moral and spiritual concept, a symbol of divine authority – was transformed into an architectural element.
What had been a living image of divine order became a piece of a mythological mechanism: a vault that holds back the waters.
When, in Genesis 7, “the windows of heaven” open, the myth is completed perfectly. Everything becomes coherent within the logic of the flood, but incoherent within the logic of creation.
The Spirit Above the Waters – the Authentic Form of the Beginning
Before this interpolation, Genesis 1 had a unified and clear meaning.
The narrative structure was as follows:
In the beginning – God and the waters: unordered matter.
The Spirit above the waters – the vertical line of divine order.
Light – the appearance of rhythm and distinction.
The expanse of the heavens – the covering of the ordered world.
The gathering of the waters – the appearance of dry land.
In this form, the “expanse” is not a separation, but a crowning. It closes the structure, it does not break it.
God no longer cuts the waters, but gathers them and covers them. Heaven is a tent, not a wall.
This image is confirmed in other Old Testament passages:
Isaiah 40:22 – “He stretches out the heavens like a tent.”
Isaiah 44:24 – “I stretch out the heavens by myself.”
Psalm 104:2 – “You stretch out the heavens like a tent, you lay the beams in the waters.”
Job 26:10 – “He has inscribed a circle on the face of the waters, at the boundary between light and darkness.”
All these texts show the same pattern: heaven above, not in between.
Rāqîaʿ is the covering of the waters, not a ceiling between two seas.
How the Flood Required a Double World
The flood myth works only in a world with two seas: one below, one above.
This is exactly the Babylonian scheme, where the “waters above” were held back by a vault, and the “waters below” formed the deep.
When the gods grow angry, the dome cracks, and the seas overflow.
In the Hebrew tradition, such a structure does not exist. Moses does not speak of “windows of heaven,” nor of “waters above.”
But when the flood story is introduced, this mythology must be integrated into the system.
This explains the modification in Genesis 1:6–7 – a retroactive “correction” made to harmonize two texts coming from different traditions.
Genesis 1 was therefore adjusted in light of the flood.
The order of creation was remodeled in order to legitimize a story from another culture.
Alexandria – Where Syncretism Becomes the Norm
This operation was fixed definitively in Alexandria, through the translation of the Septuagint (LXX).
There, the Hebrew text was passed through the language of Greek philosophy, which demanded a coherent, layered, geometric world.
For the translators, rāqîaʿ – “expanse” – seemed too vague. They chose the term stereōma – “firmness,” “firmament.”
Thus, what had been a theological metaphor became a physical architecture.
The Library of Alexandria gathered all the mythologies of the ancient world. In this environment, the translation of Genesis was not a simple linguistic transfer, but an adjustment to the intellectual standard of the age.
The result was a syncretic text that combined the monotheistic language of revelation with cosmological images from Babylonian, Egyptian, and Platonic myths.
This is the Genesis we know today: a text that contains at once traces of revelation and of myth.
But the root of the falsification remains the same: the need to support the flood.
The Nonsense of “Separating the Waters”
If we read the text without prejudice, the inconsistency is obvious.
The Spirit is above the waters (Gen 1:2).
A few verses later, God “makes an expanse between the waters” (Gen 1:6–7).
Why should the waters still be “separated” if the Spirit is already above them in Genesis 1:2? What does the text seek to accomplish through this “separation”? If the separation produces “waters above” and “waters below,” then the “waters above” inevitably remain above the expanse of heaven. But Genesis 1:14–17 clearly states that the sun, moon, and stars are set in the expanse of heaven. Therefore, the “waters above” end up above the sun, moon, and stars. Moreover, Genesis 1:20 says that the birds fly across the face of the expanse of heaven; the expanse is the visible airspace, not a lid holding back a cosmic reservoir.
The natural order is: the Spirit above the waters (1:2), the expanse of the heavens above, the gathering of the waters so that the dry land may appear (1:9).
The “separation of the waters” artificially introduces two seas out of a single one, only for the sea below to be “gathered” afterwards. This circular move resolves nothing in the narrative; it only serves the later need of the flood to have “waters above” that can pour out through the “windows of heaven.”
This contradiction is not a translation error, but a sign of compilation.
Verses 6–7 are an inconsistent insertion, introduced to create a heaven–earth architecture suitable for the flood.
In the rest of the text, Genesis immediately returns to the original scheme: “Let the waters be gathered together into one place, and let the dry land appear.” (Gen 1:9)
After the point of insertion, the text repairs itself.
The Restored Reading: Genesis Without the Flood
If we remove the mythological block of the “separation of the waters,” the text becomes clear:
In the beginning, God made the heavens and the earth.
The Spirit of God was moving above them.
God said, Let there be light.
God stretched out the heavens above the waters like a tent.
Let the waters be gathered together into one place, and let the dry land appear.
This version is perfectly coherent.
It contains no “sea above,” no “firmament” between waters, no “window of heaven.”
It is a theology of order, not a mythology of catastrophe.
Heaven is the extension of life, not the roof of a water cage.
Conclusion
The flood myth was introduced in order to provide a pedagogy of destruction.
But to make it possible, the beginning of the world had to be rewritten. That is why the expression “he separated the waters from the waters” is not a mere metaphor, but the trace of an operation of harmonization: the creation text was adapted to a myth. And to remove the myth, the text must be cleansed.
