Thanks, Mum. ;-) I should have been more obvious in my tongue-in-cheek remarks. Yes, there is so very little that adds up to any version of reality when it comes to the story of the flood.
Billy's points about the marsupials of the Australian continent are good ones. There are many others. For instance, how did giant Galapagos tortoises manage to crawl down Mt. Ararat and venture on over to some of the most remote islands in the world that happen to reside in the middle of the Pacific Ocean off the coast of Ecuador? Tortoises. Creatures the size of an ATV knew to migrate halfway around the world through oceans and continents to arrive in their paradise islands in the Pacific?
Or, how about the Tapirs. Large pig x rhino x hippo-like jungle animals that exited the ark and made a bee line trek through Mongolia, Russia, Siberia, the Aleutian Island, Alaska, Canada, United States, most of Mexico to arrive in their idilic jungle in central and south America? Oh! But wait!!! Some of those same Tapirs decided to not make the long journey with their families and so they detoured to Malaysia to settle in. But Tapirs are found in no other places on earth than the areas I already mentioned.
I could go on for days........
