Probably 100,000+. Don't worry, God made up for it by giving anyone who survived a nice rainbow.
Jehovah Purposes to Destroy That World. Jehovah set a time limit for the existence of that ungodly world, saying: “My spirit shall not act toward man indefinitely in that he is also flesh. Accordingly his days shall amount to a hundred and twenty years.” (Ge 6:3) Evidently these words were spoken to Noah.
About 20 years after that, Noah’s first son (probably Japheth) was born (2470 B.C.E.), and the record shows that another son, Shem, was born two years later. The time of Ham’s birth is not stated, but these three sons were grown and married when the divine instructions were given to Noah to build an ark. Consequently, it is likely that only 40 or 50 years then remained before the Deluge.
(Ge 6:13-18) Now, brought into a covenant with Jehovah (Ge 6:18) and assisted by his family, Noah set to work as a builder and “a preacher of righteousness,” warning that wicked generation of impending destruction. —2Pe 2:5. Preservation Through the Flood.
The people did not believe that God would act to destroy a world of wickedness. So it was because Noah possessed strong faith that he, in implicit obedience, did “according to all that God had commanded him. He did just so.” (Ge 6:22) It was because of his unswerving faith in Jehovah that the Christian writer of the book of Hebrews included him in that “so great a cloud of witnesses.”
He wrote: “By faith Noah, after being given divine warning of things not yet beheld, showed godly fear and constructed an ark for the saving of his household; and through this faith he condemned the world, and he became an heir of the righteousness that is according to faith.”—Heb 11:7; 12:1.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
