Noah's children screwed their father? All three boys?
Gen 6: 5 The LORD saw how great man's wickedness on the earth had become, and that every inclination of the thoughts of his heart was only evil all the time.
Gen 6: 11 - 13 Now the earth was corrupt in God's sight and was full of violence. 12 God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. 13 So God said to Noah, "I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth.
You don't think that those people were worse than those today?
I don't see that as being an accurate description of our society, or many others as well.

All part of God's plan. Create scads of evil people and then wipe them out.
That has nothing to do with my point.
My point is that killing millions of men, women, children, fetuses, puppies and other animals with the flood, there is no improvement in the world. Biblical history after the flood is full of corruption, warfare, genocides ordered by God, slavery sanctioned by God.
I'd say not many people would trade their lives today for that of a random person in Old Testament times. Especially considering the odds against being one of the Chosen.
