If one takes the position that Moses wrote this description on his own,
then your position would accurate, but what is proposed by the tablet
literary theory of Genesis is that Moses did not write this description.
This description comes from tablet 2 which is Adam's geneology and history.
It would thus be Adam's description of the pre-flood world and not Moses'
description of the post-flood world.
For those who are unfamiliar with the tablet theory, here is the literary
breakdown of Genesis.

The use of the words "could also..." and " likely..." and "may have..."
is to make it easier to back track if one needs to. It is a whole lot
easier to change your position when you have used such phrases, than if you
say: "Thats the way it is, so just go jump in a lake!"
