The flood story also brings up an interesting thought: doesn't it speak to god's failures?
First, we have a world that he created and populated, a creation that he 'saw was good.' It doesn't take very long for the first two humans to wreck his plans by listening to a snake and eating a piece of fruit. Fast-forward, and the entire population of the world (with perhaps eight exceptions) is so iredeemable that god decides to wipe the slate clean. He kills everyone (except those eight) along with nearly all other life on the planet. Fresh start!
One of the first things Noah does is get drunk and strip naked, and his son sees this and tells his brothers. It appears that simply looking upon his drunk and naked dad is enough to earn this son his father's condemnation. These were the only people god felt justified in saving from destruction.
Before long, humanity gets together and begins building a tower that will stand as a testament to their unity and power. God himself wonders at this, figuring that if they accomplish it, nothing might be out of their grasp. So, this is a good thing, isn't it? NO! God panics, confuses their languages, and scatters them. Disunity and conflict are guaranteed for generations to come.
And today, we watch people try to interpret and discuss the Bible. And often, there are differences that are difficult to settle because the languages the texts were written in have their own differences from our modern versions and consensus seems impossible. This is thanks to that time when god invented a bunch of languages and forced them on to people in order to divide humanity.
Jehovah is not just a wicked person; he's embarrassingly incompetent.
