First, angels started sneaking down to earth and having sex with human women, creating half-human, half-angel babies, which God did not approve of. Some of them grew to be absolutely gigantic. (Gen. 6:1–4) Thankfully, most of them had heart problems and quickly died off. But that wasn’t the real problem. The real problem was this: Humans were bad. They were wicked and evil and did awful, nasty, lawless things. (Gen. 6:11) (“Wait. Can they be doing ‘lawless’ things when I haven’t given them any ‘laws’ yet?” crossed God’s mind, but he ignored the question.) Also, they lived close to a thousand years, far too long. “Eighty years is plenty,” God muttered to himself. God decided he’d had enough; he’d given the humans a chance and they had failed (as he knew they would, obviously), and now it was time to wipe them all out. He probably should have killed Adam and Eve and started over back then, he now realized. He’d been a patient, tolerant father for a few thousand years, but that was over.
