""Young Earth Creationists, as you know, generally believe that we are all children of Noah.""

We have a basic problem here.

Four males and four females cannot possibly constitute a viable gene pool for perpetuation of any species of mammal.

Whatever else you may believe, this is an irrefutable fact of life.

The result (in the very short term) would be birth defects and disabilities which would bring their existence as a species to an unavoidable dead end.

And since you believe that only those aboard the ark survived.......four of each is all you have to work with.
