Unless you specify a example you think is appropriate to refute the possibility of there ever having been a global flood
Rainfall and expulsion of "waters of the deep" {something never specifically explained BTW}of the intensity required to produce a flood covering the entire earth is not possible due to the heat energy produced in the process which would effectively kill all life on earth excepting perhaps extremophiles. It is thus
impossible to avoid the horrible consequence of such a flood which would steam alive any creatures in the environment.
The 100% humidity would also kill animals that do not sweat {like dogs} since they depend upon evaporation of moisture from their tongues in order to cool their core temperature.It would be
impossible for them to survive a prolonged exposure to such conditions.
Ice worms
{
Ice worm - Wikipedia} and {
Page not found - Nichols College}
are incapable of surviving off glaciers in temperatures above a few degrees of the freezing point of water. In the absence of a refrigeration system{ not to mention their food source snow algae} it would be
impossible to have them aboard an ark much less survive immersion in
liquid water.
Need more examples? Just ask.
Dear Mrs Chown, Ignore your son's attempts to teach you physics. Physics isn't the most important thing. Love is.
Best wishes, Richard Feynman.
