“I said that they believe all modern species descended from those kinds that fit on the Ark.”
That’s still not accurate. Maybe you should just stop trying to speak for them, eh?
I give the floor to you then to describe your own beliefs in this. But to deny the argument of descent of species among kinds is a common one among creationists is to deny reality. And maybe if you had better reading compression you would be able to accurately understand what I said rather than misrepresenting it.
