This is true because most saints didn't even waste their time on the topic. I'm not saying it shouldn't be discussed but it's not a moral issue. If it was, then why isn't the topic in the catechism?
Now here is a sincere question. Finally!
Pax, I don't really have a sure and complete answer, even for myself, but permit me to hypothesize.
Our Lady of Fatima pray for us.
A notable Catholic, Pope or saint, once wrote (I don't have the reference and hoped someone might remember because I saw it long ago) that Heliocentrism is a denial of the Incarnation. Now, the connection is real, even if it sounds like a reach. So keep this premise in mind and let me explain:
In order for the Great Apostasy to take foothold, leading to the wholesale loss of belief in Scripture, Tradition and the Church, God will permit a Great Apostasy, punish man, conquer present evils and show His Goodness and Omnipotence in a more manifest way and bring about the glory of the Church. Now, while none of this is really new, the truth about creation was permitted to be buried, rejected and forgotten to serve this purpose.
The nєω ωσrℓ∂ σr∂єr and Great Apostasy are based in Heliocentrism and scientism, which are the sources of many modern errors like the Big Bang, Godless creation, evolution, scarce resources, global warming, divisions, feminism, abortion, worship of animals, scientific lies that enrich the wealthy, global control, enslavement of man, self worship and occult practices. Heliocentrism is the
physical, scientific bulwark of the Luciferian religion, because by it, mankind CHOOSES to believe the Satan's re-creation of the world over God's version of creation. After all, God starts "in the beginning" so Satan had to start there, too. Satan's religion is a "global" affront against God, Scripture and the Church. And guess what? Most everyone believes Satan. I can't tell you how many times I've heard Catholics say about FE passages, "We aren't supposed to understand Scripture literally." Or, regarding Galileo they say, "The Church was wrong." All courtesy of the chaos that comes from a spinning, whirling, barreling, contradictory foundation.
Our Lady made the sun dance at Fatima, a visible reminder that the sun moves, not the earth, which was a massive confirmation of God's version of creation virtually lost after Galileo. Ultimately, through Mary's intercession, all Catholic truth will prevail, the glory of the Church will ensue, Satan's false doctrines will be conquered, and finally, mankind will more readily understand that even in the corporeal, all things point to the Incarnation, that God really was made Man and Jesus is "Emmanuel".
