What was the point of the flood?

According to Genesis man had fallen from God's graces due to the disobedience of Adam and Eve. If we are to believe the scriptures between chapters 3 and 6 man continued to decline morally and lived only to satisfy the pleasures of his flesh. After some time God became weary and decided: ⁵ Yahweh saw that human wickedness was great on earth and that human hearts contrived nothing but wicked schemes all day long.

Now before we move on I would like to point out that this verse alone challenges the so called claims regarding the attributes of God. Namely, omniscience (all knowing/ infinite knowledge). The reason I say this is that upon closer examination of the text it seems that God was surprised at how man had turned out. So much so that the very next verse says:  ⁶ Yahweh regretted having made human beings on earth and was grieved at heart.

The Sage dictionary defines regret as: sadness associated with some wrong done or some disappointment. Why would God be sad if he already knew that this would be the outcome? If he was truly omniscient he would have known that his so called "good" creation was going to be a bust.

Now what was Hitler ooops I meant God's final solution? Well in the very next verse he makes it known: ⁷ And Yahweh said, 'I shall rid the surface of the earth of the human beings whom I created -- human and animal, the creeping things and the birds of heaven -- for I regret having made them.' Again he emphasizes that he regrets having created not just mankind but all living things.

If we were to use the allegory of disease in regards to sin and a corrupt nature then I could see the logic in destroying all forms of life and starting from scratch. If you had a deadly plague spreading rapidly across a region and was able to contain and exterminate the infected to eliminate further spread and infection then I could agree with such an action and it would make perfect sense. But this is not what the great and knowledgeable God did. For it says in verse 8 that: ⁸ But Noah won Yahweh's favour.

Now here is the kicker, how could one man gains favor with God is he also inherited the curse of God upon all of mankind? Since the fall of man in the garden man was cursed and so were all the future generations. God's curse was like a genetic disorder and as such would not just disappear.

The purpose of the flood was to cleanse the Earth from all wickedness, yet he does not fulfill this by sparing on of the "infected" and his family. And as expected his descendants did exactly like their previous ancestors had done. They ended up going back to their sinful ways and pissing God off once again.

Now in verse 13 you find a huge contradiction in motive for God: ¹³ God said to Noah, 'I have decided that the end has come for all living things, for the earth is full of lawlessness because of human beings. So I am now about to destroy them and the earth. Notice that he said that not only will he destroy all living things but also the earth! If this was his plan then why tell Noah build yourself an ark? In fact why spare Noah at all since as I stated earlier he was infected with God's curse against humanity through the fact that he was part of the human race?

So I have to ask, what was the purpose of the flood? He killed every living man and beast on the face of the earth, except those he let live on the ark. Only to end up back at square one. Then he waited thousands of years before he sends his son the perfect sacrifice to redeem man and begin a new covenant with man.

This chapter undermines the so called omniscience of God. It demonstrates that he does not know everything nor how things will turn out in the future. God is a bad planner and basing ourselves on the Old and New Testament a bully and a tyrant. Luckily for us he does not exist, and these tales are nothing more than myths and legends that have no objective means to validate their claims.
