Things that make you go, "Hmmm..." (in the Bible)

I haven't kept up with the thinking-about-the-Bible posts, but I have been thinking about some of the weird stuff found in its pages. Before I continue with weird stuff from Genesis, what are some of the weird things that you've read or heard about from the Bible or from the Bible lessons you've been taught?
To be fair, much of the stuff I just accepted as a kid or even as a learning adult. You make this assumption that the people teaching know what they're talking about, but really they just know what somebody else that didn't know jack shit taught them. 
Conservative Christians are in this culture (emphasis on cult) that doesn't allow for questioning the content or counters questions with some "That's just what I've been taught," bullshit.

In Genesis 6 we find that the sons of God see that the daughters of men are pretty hot and decided to rape them at will. The offspring are basically giants and things on earth are going to hell in a hand-basket. This apparently catches our omnipotent and omniscient God by surprise. God regrets ever having created man and decides to wipe out humanity. Not being much of an animal rights activist, killing all the wildlife is just collateral damage, but God decides to preserve each species by saving a few to reproduce and repopulate the earth. 
God finds one family of humans that aren't totally corrupt and uses them to accomplish the goal of saving the animals and restarting the human population, as well. Man, talk about your shallow gene pool! 

The whole idea of spiritual beings taking on human form and raping women to birth some kind of super beings that corrupt the earth is bizarre enough without the part about God tossing up his hands and destroying all of (well, most of) creation. 
Seriously, wouldn't you scrap the whole thing and start over--new heaven, new earth, new beings. I'd probably skip the snake part of creation and I'd reconsider that idea of putting knowledge and eternal life in fruit trees, for sure!
And yet conservative literalists will insist that it happened just so and the universe is only a few thousand years old, science be damned!

I guess the thing I don't get is this--
If you are going to make up a creation story, wouldn't you come up with something better than a bumbling god that doesn't know what he's doing and can't keep control of his cosmic experiment?
If you ask me, this whole Judeo/Christian Old Testament is pretty much a power grab for control of humanity. It makes a base that's difficult to overcome with the idea of a New Testament savior. 

Reconciling evangelical deconstruction is difficult at best. Trying to figure out the stories of a book that are obviously not infallible nor inerrant is torture for a mere layperson like me.

What makes you pause and go "Hmmm...?"
Maybe we can figure some of it out together.
