I'm telling you guys, it takes 40 days and 40 nights. Maybe it sprinkled a few days before it rained too. Think it out.
Sun, red skies, and factor in other things that may be trying to stop it.
The flood didn't happen in one day...
Maybe it isn't as everyone has pictured, like blam. Maybe the pink skies are the turning to red. Just like the seas are turning here and there. And the meteors are here and there.. Just think it out... :)
