In regards to that; if God saved two of each kind of animal on the ark. Wouldn't a lion eating a zebra, or a gazelle, or any other animal eating another animal, completely wipe out that species? And if God simply "recreated" that particular animal, then saving the animals 2 by 2 would have been pointless in the first place.
Also in regards to the flood...
If man had become so evil that God felt she needed to wipe them all out, then why leave any man living at all? Noah, his children, and all of their descendants, as a human where BORN naturally sinful. The world once again becoming a dark, evil, sinful place was inevitable as long as men maintain his sinful design. If God really wanted to eradicate sin, he would have eradicated man completely, and starting the world over with the way that he originally wanted us to be.
Oh...
So much I want to express!!!!
