Yes, interesting. If education results in less religion, then the next question is "why?" What is being taught in the education system such that people become less religious? They aren't being directly taught arguments against the existence of God, of course, so something else is going on. I'd be interested to know what that is.
Scientific education certainly results in less religious belief, e.g., in such things as miracles and the supernatural. And it's really undeniable that the whole basis of religions such as Christianity is dependent on miracles & the supernatural.
Other types education (e.g., music, history, art, … anything else), however useful they may be, are not directly explaining to you how the world around us works. So it's not just
any education that reduces religious belief, it's really an understanding of how and why science does accurately explain all the things in the world that were once believed to be deliberate acts of intelligent design from a supernatural heavenly God.
Well, that's exciting! What are three gaps where people said that God was the explanation that have gotten smaller in the last 50 years of scientific enquiry and observation?
Does it have to be 3 gaps in the last 50 years? Because it's absolutely undeniable that over the last 200 years or so (and increasingly over the last century), scientific discoveries have given convincing explanations for ”all” the things that were previously thought to be acts of intelligent design from God. That is “all” except for possibly (1) how the first living things formed on Earth, and (2) exactly what happened to cause the Big Bang. Although even in those two cases there has been a great deal of research since the 1960's, and there are now a number of quite plausible explanations as to how both of those things probably happened …
… and unless people are being deliberately disingenuous, then we have to accept that those two issues are perhaps unusually difficult to solve with anything near to “certainty” (ie reaching the level of a “Theory”), because apart from anything else they both happened billions of years ago (which makes it harder to study exactly what happened).
But also, in both cases (the origin of life & the Big Bang), science has already discovered what is unarguably 99.9% of the explanation. For example, we know know very accurately what happened right back 13.8 billion years to within about 1 second after the “Bang” … so religious people and others are really left arguing about exactly what happened in that first single second, whilst trying to ignore the vast in-depth explanation that we now have for the rest of that 13.8 billion years.
And similarly with life on Earth, where evolution can now account very accurately for the existence of every known species that ever lived on Earth, right back to the first single-celled organisms about 3.5 billion years ago. So that creationists are now left arguing about the last tiny “gap” where aggregates of chemicals passed from what we define as “non-living” to “living”, but where, as we get to that transition point, it may well be the case that there really is no clear dividing line between what we should properly regard as chemical aggregates that are living vs those that are not quite living.
