Where Did the Water Come from for the Great Flood?

By Dr. Arv Edgeworth

“For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.”

Genesis 7:4


Where Did All the Water Come from for the Great Flood?

We have 4 possible hypotheses that have been given:

(1) A Water Canopy

(2) Plate Tectonics

(3) Hydroplate Theory

(4) A Supernatural Act


It has been proven using scientific models that a water canopy, plate tectonics, and hydroplate theory have serious scientific problems for being a viable hypothesis. I won’t get into all the details on those in this newsletter. But the only viable hypothesis left is a Supernatural Act.


It might be important for us to consider the other Supernatural Acts of God in Gen. 1:

a. He spoke the Universe and Earth into existence from nothing. v. 1

b. He spoke “light” into existence from nothing. v. 3

c. He spoke a “firmament” into existence from nothing. v. 6

d. He formed a series of water basins in the earth’s land surface (“Seas”). vs. 9-10

e. He spoke plant life into existence. vs. 11-12

f. He spoke the sun, moon, and all the stars into existence from nothing. v. 14

g. He created all the sea life and fowl. vs. 20-21

h. He created all the land creatures. v. 24

i. He created man. v. 26


Consider this:

When God brought all those stars, said to be millions of light years from earth, into existence on day 4, He did so in such a manner that Adam could see them two days later.


The Supernatural Cause of the Great Flood:

“For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.”

Genesis 7:4

An Example in Scripture:

In 1 Kings 18:41-46 there was no sign of rain, then Elijah prayed:

v. 45 “And it came to pass in the mean while, that the heaven was black with clouds and wind, and there was a great rain. …”


At the Time of the Flood:

As the appointed time arrived for God to send the deluge, picture heavy cloud formations (Nimbostratus clouds) gathering overhead for the very first time. Then began a heavy downpour which would last for exactly 40 days and 40 nights. Then God stopped it. Or perhaps the water from the “great deep” spewed forth and fell to the earth as rain.


Two Possibilities:

(1) God caused cloud formations to start gathering, and then began a heavy downpour.

(2) Perhaps God opened the giant reservoirs down deep within the earth, which then began to spew water high up into the atmosphere, which then began to fall as heavy rain.


With either possibility, we know one thing for sure, it was supernaturally caused. In Genesis 7:4 God said: “For yet seven days, and I will cause it to rain upon the earth forty days and forty nights;”

Some scientists have assumed God needed a natural source for 40 days and 40 nights of rain. 


Consider the feeding of the 5,000. Consider the manna from heaven. But we also need to consider the giant reservoirs deep within the earth.


“Ah Lord God! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee.”

Jeremiah 32:17
