The Church has not been “bending over backwards” regarding this. It is constantly being challenged by those looking for anything to confirm the Church agrees with it. Not so. As early as 1950, Pope Pius XII wrote in 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. However, this must be done in such a way that the reasons for both opinions, that is, those favorable and those unfavorable to evolution, be weighed and judged with the necessary seriousness, moderation and measure, and provided that all are prepared to submit to the judgment of the Church, to whom Christ has given the mission of interpreting authentically the Sacred Scriptures and of defending the dogmas of faith.[11] Some however, rashly transgress this liberty of discussion, when they act as if the origin of the human body from pre-existing and living matter were already completely certain and proved by the facts which have been discovered up to now and by reasoning on those facts, and as if there were nothing in the sources of divine revelation which demands the greatest moderation and caution in this question.”
In other words, there is a for and against and the Church has the authority to have the final say.
Pope Benedict, regarding the often quoted statement by Pope John Paul II, added that - especially regarding the human body - that this alleged series of changes cannot be reproduced in the lab and so cannot be verified.
And yes, Adam and Eve were two literal individuals who were responsible for Original Sin which is passed on to all by generation since we all descend from that couple. It is necessary for our salvation to know this. One: we have a physical body and a spiritual body or soul which is immediately created by God. Two: Jesus Christ was not born into this world for no particular reason. Because of Original Sin, He died as a sacrifice for all and rose from the dead, literally. John the Baptist baptized with water but Jesus told us baptism would be with water and the Holy Spirit. He established His Church and gave us much more information about how to live because He was true man and true God.
But I can guarantee one thing: these threads will appear again and again. And again. This suggests supporting atheism.
