"After the Flood, the marsupials left the Ark and dispersed around the world. They could have dispersed before many of the other mammalian varieties. They occupied various niches around the world, but were eventually driven off by competition in Europe, Africa, and Asia. Finally, they ended up establishing themselves in more distant (vis--vis the Middle East) regions. As ocean levels rose at the end of the Ice Age, land bridges were eliminated and the migrant marsupials were stuck where they were.10 There’s also evidence suggesting that human travellers introduced some of the marsupials to distant lands, which can explain conundrums of very similar marsupials in different parts of the world.11"
A few problems:
--There is no evidence for a flood.
--There is no evidence for an ark.
--There is a lack of marsupial fossils in recent times in Europe, Africa, and Asia.
--The flood is supposed to have occurred some 4,350 years ago, while the most recent ice age faded away well over 12,000 years ago.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
