"Good" does not necessarily mean "perfect". There is no
biblical basis for the common western belief that Adam & Eve were
extraordinarily beautiful, intelligent, perceptive, &c. Much less is
there any basis for saying that they had "perfect genetics" - whatever
that may mean.

This is effect makes Satan the creator of the world as we know
it, & thus approaches the Manichean heresy, according to which an "evil
God" is the creator of the (evil) material world. It is a large scale
version of an extreme idea of original sin which was condemned at the
time of the Reformation (Formula of Concord, Article I), which said that
original sin was the substance of fallen human nature.
