Yeah, yeah, yeah...
The creation fundamentalists will change Gen 5:2 just the way you say.
But the point of the Theistic Evolutionists is that Gen 5:2 clearly says in the KJV that this man and women represent a species which is a foundtion for all other claims about the 22 now extinct humans right for the literal text of the Bible, itself.
Another false appeal to authority.
Theistic evolution proponents endorse no such position.
There are no other claims about 22 species. That's your private and solely held position.
