. . . Where are the kangaroo fossils?
I'm not 100% sure because I did not have my camera with me then. But I believe it's possible kangaroo ancestors walked
off the ark.
But, even if that had been the case, there are many more seemingly unexplained scatterings of animal species for whch we have only speculation. And how did that box even float? We could ruminate endlessly over the list.
So why believe the flood account? I have a number of reasons. One that I find intriguing is the similarity between the "sons of the true God" marrying women, the traits of their offspring, and the religions of Greece and Rome. Coincidence? Post hoc transcription? Maybe. The words 'satan' and 'titan' both essentially mean 'rebel'.
Lots of other things - the universality of flood stories among diverse socioethnic groups is another. I could go on until your eyes glaze over.
The bottom line is partly in the object lessons for us:
Noah obeyed to the letter.
The folks who died knew of the demonic violence in which they lived, but were more concerned with ordinary life than with Noah's clear warning.
Whatever Noah may have lacked, God certainly had the power to provide.
