It is my Biblical Opinion.. In order to understand Noah's Global Flood, one must understand the following:
The world of Adam was an enclosed Biosphere much smaller than our earth, which was totally surrounded by the firmament which protected it from the water below and above it into which it was placed. Gen 1:6-8 - while our own present world is surrounded by Star Dust. Adam's Earth was not on a Rocky Planet, like our present Earth, since it was "clean dissolved" in the Flood, and rocks don't dissolve in water. Isa 24:19
This Earth, the Earth of Adam, was considered FLAT by the Ancient Hebrew Perspective. It's highest point is only about 22 1/2 feet above sea level, Gen 7:20 .... while our earth’ highest elevation is some 29k ft. above sea level in comparison. Their entire Earth had only 4 Rivers while our present World has thousands of Rivers all over the face of the earth, indicating it was much much smaller than our Earth.
Here are some model images of Ancient Hebrew Perspective of Flat Earth -simili - for reference only - Adam's firmament of heaven - surrounded by waters below and above it .......Ancient Hebrew Cosmology
During the Great Flood, Noah and the Ark were 22 1/2 ft above Adam's Earth on the 150th Day after the Flood began. At this depth the mountains of that Earth were covered in water. Gen 7:20. On the SAME 150th Day after the Flood began, the Ark rested upon the mountains of Ararat. Gen 8:4
That's one of the mysteries. HOW could the Ark be in both places on the SAME Day?
