Thank you, Danny. The point of my article was that 100 years ago, most scientists (based on polling then and now) were non-believers, and today, most young scientists believe there has to be a God, higher power, or divine creator because so much of what we've learned over the past century shows that the Universe and our planet wouldn't be holding together without a creator making it all work.
You raise some important points I didn't attempt to tackle, but here's something that may or may not help: First, about hell. The Catholic Church has never said anyone (by name) is now in hell (not even Judas or Hitler), so they certainly don't have a hard number or percentage on how many might be there (so we can't say most are in hell). The church does teach that hell is real and saints have had visions of hell (where they saw many). But some theologians (including Bishop Robert Barron) have argued it is possible that no one is in hell because redemption is always possible, and God is always trying to reach us and wants to save his children. One more interesting point on hell: Father Gabriel Amorth, the Vatican exorcist until his death a few years ago, was arguing with a demon who told him God didn't create hell: that we created it ourselves. And the Church teaches that everything God makes is good. Hell, by definition, is where we choose to go if we choose to be in a place where God can't reach us. And hell is the only place where God won't go. He lets us choose. Bless you, in your quest as well!
