I can't believe all you flood denyers! Well there are good reasons for all fo those things.
1) Amount of species. Well duh.....Noah put them in the ark "according to their kind", which means you have a set of wolves in there, and then "hyper-evolution" (I made that up but I like it), resulted in the species we see today. About 11-133 new ones every day using modest stats. Hey a new species just flew by my window!
2) Sure it was cold at 35K feet, but they probably didn't use feet back then.....but who knows HOW TALL the mountains were back then. Sure they grow at a snails pace now, but back then they grew faster. Ye of little faith. Of course, with that amount of animals, dung feces, and food, they had all they needed locked in tight to be able to keep warm. Just think of the methane usage alone! I am sure they burned that for heat.
3) Kangaroos do what?......they hop! So they made it to Australia. I mean it only takes two right? They could have hopped on driftwood and dead carcass. The bloated corpses of human being could serve as both food, AND flotation devices.
4) Insects.....duh....they ate the crap. It solves the other "issue" you dang flood denying apostates have brought up of animal waste and lack of oxygen.
5) Water came from the cloud canopy AND from underground well springs. I mean just look at the trailer for Noah with Russell Crow and see for yourself!
6) Rainbows are proof!
In all seriousness, my mother told me she thought the reality of the flood was one of the hallmarks for the bibles accuracy. She said they have found animal skeletons in caves where predators and prey were all together trying to escape something.....so that was pretty much it for her.
Ugh.
