8:1 Then God remembered Noah, and every living thing, and
all the animals that were with him in the ark. And God made
a wind to pass over the earth, and the waters subsided. 2
The fountains of the deep and the windows of heaven were
also stopped, and the rain from heaven was restrained.3 And
the waters receded continually from the earth. At the end of
the hundred and fifty days the waters decreased.4 Then the
ark rested in the seventh month, the seventeenth day of the
month, on the mountains of Ararat.5 And the waters decreased
continually until the tenth month. In the tenth month, on
the first day of the month, the tops of the mountains were
seen.
Where did the waters go? Well God says that the wind
began to blow and much water is then absorbed in the
atmosphere. I have no idea how much water we regularly have
in our atmosphere but it is significant. In addition, if the
waters had come from below the depths of the seas then the
cavern left by the water escaping would create a vacuum that
was filled by part of the crust lowering, like the western
pacific basin indentations(see attached map). Some of the
water obviously became frozen as glaciers and as an ice age.
Frozen water over the seas does not change the sea level but
water frozen on land does lower the level of the seas
marginally. The attached map does represent underwater
canyons that are miles deep pressed into the earth. With a
cooling of the caverns vast amounts of water could have been
returned from whence they came. Then again God could have
supernaturally removed the water too!

6 So it came to pass, at the end of forty days, that Noah
opened the window of the ark which he had made.7 Then he
sent out a raven, which kept going to and fro until the
waters had dried up from the earth.8 He also sent out from
himself a dove, to see if the waters had receded from the
face of the ground.9 But the dove found no resting place for
the sole of her foot, and she returned into the ark to him,
for the waters were on the face of the whole earth. So he
put out his hand and took her, and drew her into the ark to
himself.10 And he waited yet another seven days, and again
he sent the dove out from the ark.11 Then the dove came to
him in the evening, and behold, a freshly plucked olive leaf
was in her mouth; and Noah knew that the waters had receded
from the earth.
It took awhile for life to begin again with most of the
vegetation probably washed away in waves of water and mud
but what remained and the seed that fell to the ground
quickly sprouted again to restore life. The dove and the
olive being to symbols of Gods love, peace and healing upon
the land.
12 So he waited yet another seven days and sent out the
dove, which did not return again to him anymore.13 And it
came to pass in the six hundred and first year, in the first
month, the first day of the month, that the waters were
dried up from the earth; and Noah removed the covering of
the ark and looked, and indeed the surface of the ground was
dry.14 And in the second month, on the twenty-seventh day of
the month, the earth was dried.
It must have been strange because the Earth would have
changed from before the flood. There no longer remained the
four great rivers heading throughout the Earth. The cities
and the people all gone but here was a chance to go out and
start anew.
15 Then God spoke to Noah, saying,16 "Go out of the ark,
you and your wife, and your sons and your sons' wives with
you.17 "Bring out with you every living thing of all flesh
that is with you: birds and cattle and every creeping thing
that creeps on the earth, so that they may abound on the
earth, and be fruitful and multiply on the earth."18 So Noah
went out, and his sons and his wife and his sons' wives with
him.19 Every animal, every creeping thing, every bird, and
whatever creeps on the earth, according to their families,
went out of the ark.20 Then Noah built an altar to the LORD,
and took of every clean animal and of every clean bird, and
offered burnt offerings on the altar.
Finally Noah went out and rather then mourn the loss He
gave thanks for God delivering him and his family. God noted
what this righteous man had done.
21 And the LORD smelled a soothing aroma. Then the LORD
said in His heart, "I will never again curse the ground for
man's sake, although the imagination of man's heart is evil
from his youth; nor will I again destroy every living thing
as I have done.22 "While the earth remains, Seedtime and
harvest, Cold and heat, Winter and summer, And day and night
Shall not cease."
Then the Lord promised Noah He wouldn’t do it again until
the Earth ceases to be. They went out to be fruitful and
went throughout the World until the days of Peleg but that
story is still to come.
