Noah's Ark, Kangaroos and Australia
It's God's Will. He picked up the bones in order to test your faith. He's cunning like that. Like when he put old dinosaur bones in the ground to test your faith that the world is only 8,000 years old. Don't believe all those scientists. They'll only teach you things.
God doesn't require Noah to respawn the earth. It's just a test of Noah's faith. What Noah saved are those animals promised to reappear in the future earth. so that part of the story is just a prophecy on What to be conswrved in the future, not today's world.
"Answers in Genesis" does address this, but it's such a painful exercise in motivated reasoning (sprinkled liberally with what the old fashioned folks call "lies",) that I couldn't get through it. It's really a shame, Biblical literalists give religion a bad name.
According to Dooley (my canine mate , I'm Rob) the bible got it wrong. The ark first visited Ararat not far from us. Ararat is in western Victoria, Oz. Dooley is quite knowledgeable on such matters as he his a proactive paleontologist, that is, he buries bones as well as digging them up.
