According to the origins theory model used by creation scientists, modern kangaroos are the descendants of the two founding members of the modern kangaroo baramin that were taken aboard Noah's Ark prior to the Great Flood. It has not yet been determined by baraminologists whether kangaroos form a holobaramin with the wallaby, tree-kangaroo, wallaroo, pademelon and quokka, or if all these species are in fact apobaraminic or polybaraminic.

After the Flood, these kangaroos bred from the Ark passengers migrated to Australia. There is debate whether this migration happened over land[5] with lower sea levels during the post-flood ice age, or before the supercontinent of Pangea broke apart[6], or if they rafted on mats of vegetation torn up by the receding flood waters.[5] The idea that God simply generated kangaroos into existence there is considered by most creation researchers to be contra-Biblical.

Conservapedia.com was created by religious conservatives convinced that Wikipedia has a liberal bias that needs to be offset by active promotion of their own view. It is self described as:

A conservative encyclopedia you can trust with over 7,200 educational, clean, and concise entries.

It is interesting that belief has become a matter of personal decision rather than being directly derived from experience. It is a shame what can happen when the hands are extracted from learning.
