The footnotes link to sources providing detailed research behind each topic.Australian marsupials provide a humorous visualisation to conceptualise the issue with a global flood.
The Watchtower takes literally the Genesis account of a global flood that covered the top of earth's highest mountains.
This article addresses an array of evidence regarding whether it is possible that a global flood occurred 4,400 years ago.
Possibly there were also other ridges, and animals could have migrated by means of these before such ridges sank below the surface of the ocean.
Other oceanographic studies have turned up evidence that once there existed a huge South Pacific continent that took in Australia and many of the South Sea isles.
Although the arguments presented for a flood are from Watchtower publications, little of this originates with Watchtower writers, but borrows heavily from fundamental Christian sources.
Following are key areas to consider when deciding if a global flood is possible, presented in layman's terms.
Marsupials live predominately in the Southern Hemisphere.
Koalas and kangaroos are only found in Australia and the Tasmanian devil exists only on the small island of Tasmania, at the southern most part of Australia.
The Watchtower uses the argument that a land bridge existed for marsupials to cross.
