If all the surviving animals disembarked at Ararat after the deluge, how did various species end up where they?
How did the Rheas, being flightless, get from Turkey to South America? Did they walk? How did the polar bears get to the Arctic, given their need for cold temperatures, frozen oceans, and toothsome seals? It must have been a long, hungry, hot trudge across the Caucasus. How did those troublesome kangaroos get to Australia? Exactly how far could the bloody things jump?
If the kangaroos hopped from Ararat to Australia, why had none lingered in Asia? If the cockatoos had flown out from the ark (as the raven and the dove had done earlier, on their scouting missions for dry land) and headed southeast, why did they fly all the way to Lombok before choosing to stop and establish a presence? Why had they spurned all the intermediate terrain? What had been so off-putting about, say, Bali?

Do you hate biology or something lol? If you go to a public school this is all based on evolution. Ick! Darwinism is so confusing, but he had some good ideas. I mean you can do research to find out how animals migrate. And it may have happened because of the great flood or land shifting events...

Well, it all depends on what you believe. Yes, that touches evolutionism and your faith.

Whatever you choose to believe in, it's your choice and nobody can actually force you to believe the opposite. They can give you ideas to think about, but not put the though within you.

Personally, I for some animals, I think that people took them from one place to another. Some kept them, others perhaps killed them for food, hence explaining their disappearance in certain regions.

Note that the Arctic is melting, and this can mean that long ago, the continent of Asia was connected to the Arctic by ice and that the polar bears were able to get there.

There are numerous things that cannot be proven for the time being, given the apparatus we use now. Maybe later on, we'll have a better idea of what really happened long ago.

Until then, you can still keep those in mind, and try to make logical conclusions for you. I may not be right about my thoughts, but I don't think that anybody can say for 100% sure his thoughts are the true facts that happened at that time.

bluesky42 (1 post) is trolling and rather funnily.

Biogeography is one of the major arguments for evolution, along with the incontrovertible fossil record, which shows a consistent and understandable record of change over billions of years.

Kangaroos and all the other Australian marsupials evolved in Australia. Their nearest relatives are in South America, with one marsupial in North America--the opossum. There was no land bridge from Biblical era Mount Ararat to Australia.
