Why not just do one more miracle and send a pink flying carpet down to pick up Noah & the rest? Or why not just "neutron bomb" the baddies and the nephilim?
This is why Jehoober will never be put in charge of any project in a modern day corporation. Jehoober evidently chooses the hardest, most intricate way to accomplish a simple task.
I mean, imagine going to the lenghts of creating a logistical nightmare of flying animals along with their specific foods, over oceans and building large wooden floating boxes, while creating a catastrophic annihalation of 99.9% percent of all animal, and plant life via a deluge, only to kill a few humans, when this could have been accomplished by a few angels in a matter of hours.
Well done Jehoober.
