Who Fed-Exed the kangaroos to Noah?

Umm, nobody, how do you know that before the flood,the world wasn't a different palce, and kangaroos lived where Noah lived, and not just in present day Australia? I wish I had time to explain it all to you, but the basis is this: a worldwide flood can drastically change the landscape of this Earth, and when it did, temperatures changed, mountains, valleys, rivers all changed, and where the animals adapted too changed as well.
