There is no reason to believe that Noah’s family were the only innocents in the Flood story. I do not know how one can pin the supposed hedonism of the world on all those young children who would have drowned.
There is also no way to excuse killing the children of thousands of people because of the actions of one man. Blaming that one man for “forcing” supposedly omnipotent being to act in that way is also unjustifiable.
And there is no way to shift blame for genocide by simply saying, “the underlings took it too far.” This excuse rings especially hollow when Jehovah asks for a cut of the spoils afterward (Numbers 31:25-31).
In the Sodom and Gomorrah story and the Jericho story, innocent people were saved. How would the great flood be any different? It’s illustrative of the extent of the hedonism.
You can’t even keep your own stories straight. The Great Flood myth in the Bible is very explicit that all life on earth will be destroyed, except that aboard Noah’s Ark. Genesis 7:23 (NIV):
“Every living thing on the face of the earth was wiped out; people and animals and the creatures that move along the ground and the birds were wiped from the earth. Only Noah was left, and those with him in the ark.”
It wasn’t a global flood. It was hyperbole. 2 Peter 2:5 says it just covered the world of the ungodly. “World” is generally used locally in the Bible as well as “the earth” meaning a large area of visible land.
We can see that in Genesis 8:9
“But the dove found no place to set her foot, and she returned to him to the ark, for the waters were still on the face of the whole earth. So he put out his hand and took her and brought her into the ark with him.”
When verse 5 said:
"And the waters continued to abate until the tenth month; in the tenth month, on the first day of the month, the tops of the mountains were seen."
