You've missed part of the thread.
That's been covered.
And, you and he both must have mised it too...
The perplexing question of human origin from a common ancestor to apes is even more problematic. According to evolutionary theory, humans (homo sapiens) did not descend from apes, but from some missing link. Although Dr. Louis Leaky spent decades searching and found zinjanthropus and homo habilis, Olduvai Gorge gave no answers. Logic also suggests in order to descend, there has to be something you descend from and something you ascend to.
Evolutionary theory, rooted in the universal human dissatisfaction for mortality is a vain search for human origin(s), an attempt to rationalize a yearning for connection to something eternal.
Now, since nobody really knows the answers, it is only a scientific method to consider all points of view on the issue in educational settings. To do otherwise would be like students dancing around totems, with professors as witch doctors proclaiming intellectual taboos and making sacrifices.
This is far worse than what the ersatz secularists accuse the creationists of doing!
