Which of it is false? I have read the much of the Fathers and find very little evidence of a doctrinal position regarding creationism, Theistic Evolution is an accepted position by the Church
[quote=‘HH Blessed Pope Pius XII Humani Generis 36’] For these reasons the Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter - for the Catholic faith obliges us to hold that souls are immediately created by God.
Within St. Augustine of Hippo, Doctor of the Church, he criticized those that ‘foolishly’ tried to turn the Scriptures into a Science Book, and warned that we shouldn’t form an opinion, lest he be found we were wrong due to our mistreatment of Scripture.
As for Theistic Evolution or a form of intelligent design (or even simply scepticism in all directions) this is this likely position for the Hierarchy (I have yet to meet a Priest or Bishop that holds to creationism) as it holds a greater ground within the Christian tradition.
