"...beast of the earth, after his kind"
This phrase presents a problem later on in the Noah story (Genesis 6).
Presumably, this represents creation of ALL the species of animals as we now know them
and the approximately 10 million species that have gone extinct since the creation.
Thus ALL of these "beasts of the earth, after his kind" had to have been
on the Ark!
Ark apologists claim that "kind" doesn't mean "species" but instead means "genus",
thus allowing for far fewer animals on the ark.
Here, though, we learn that "beast of the earth, after his kind" really
does mean "all the animals that ever existed".
