Or don't you believe that is true either?
When I was a Catholic, eons ago, I was in Catholic school religion class. Most of the time, I was too busy looking at the girls, instead of paying attention. One time, however, I remember the priest said he thought the Flood was just a local thing, covering Israel, and maybe part of Jordan, Syria and Saudi Arabia. I actually believed that drivel.
Now that I am an ex Catholic, I know it was a world wide event.
I have heard estimates, that maybe 150 million people may have been killed in the Flood. That's a lot of "innocent" people. Oops, sorry, only Jesus was innocent.
I don't know why God did that, but He has His reasons. I am not sure if it was related to the nephilim. ,
The book that the Catholics assembled (they got THIS part from the Jews) said they were around in those days.
4 The Nephilim were on the earth in those days - and also afterward - when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
5 The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. 6 The Lord regretted that he had made human beings on the earth, and his heart was deeply troubled. 7 So the Lord said, "I will wipe from the face of the earth the human race I have created - and with them the animals, the birds and the creatures that move along the ground - for I regret that I have made them."
8 But Noah found favor in the eyes of the Lord.
It does NOT say the GIANTs mated with the Humans; it merely says they were on the earth. ??? So; just WHO are the sons of God and the daughters of humans??? The BOOK says: Let Us create Man in Our image. So there you get some 'sons of God'; right?? The BOOK also says, in Genesis 5:3-4 When Adam had lived 130 years, he had a son in his own likeness, in his own image; and he named him Seth. 4 After Seth was born, Adam lived 800 years and had other sons and daughters. These things happened BEFORE Genesis chapter 6....
No one was innocent then. The thoughts of the people were only evil continually.
There was no good left.
If the entire planet was covered by water(40 days and nights wouldn't have done it) to the height of Mount Everest....where did all that water go?...29,029 feet of water is a lot of water.....that's 6 miles deep.....EVERYWHERE.
