God’s an unfalsifiable claim, so there really isn’t anything that could test that hypothesis.

Pretty much any scientific test/discovery that counters anything in a religious text whose adherents view the text as completely truthful and literal. But sciencey stuff might not have much of an effect on religious folks who view their texts less literally.

But anyways… heliocentrism, germ theory, gravity, evolution through natural selection, probably a huge chunk of the field of archeology, plate tectonics, radiometric dating, probably the written language at various points in human history (but that’s not really a discovery), trans species organ transplants, decoding DNA, direct genetic engineering, CRISPR, radio telescopy.

Nothing u cant prove a negative.

It wasn’t any particular scientific discovery that weakened religion. It was the popularity of science fiction that did it. As Arthur C. Clarke put it, “Any sufficiently advanced technology is indistinguishable from magic.” People can now imagine how miracles are done without invoking anything supernatural. We might not have the tech to do it yet, but we have a pretty good idea of potential methods. That has placed a lot of “creator god” religions under pressure. Create life? Tech will eventually do it. Create a world? Sure, tech again. Given enough tech, a solar system can be spawned. Water into wine? We’re halfway there with Kool-Aid. We already have vimanas (those ancient Hindu flying vehicles). We call them airplanes or helicopters. We can destroy a whole city with a single weapon. So why should we worship a supreme being who supposedly did those things?

Assuming we can conquer poverty, religions that survive will be centered around improving the human condition. Worshipping dieties will eventually fall by the wayside. It will still be a long process. You can’t dispel faith with reason and facts. And people in poverty tend to embrace religion because it gives them comfort and hope that things will be better in the afterlife.

Your birth.

I’ll quote Tim Minchin here

"If you wanna watch telly, you should watch Scooby Doo
That show was so cool
Because every time there was a church with a ghoul
Or a ghost in a school
They looked beneath the mask and what was inside?
The fucking janitor or the dude who ran the waterslide
Because throughout history
Every mystery
Ever solved has turned out to be
Not magic"

Science and religion are often compatible, I know of some Hindu thinkers (for example) who say scientific knowledge is to be taken as truth and religious truth should not contradict it - just that this scientific knowledge cannot explain the whole mysteries of the cosmos. You might be aware of “the god of the gaps” and arguments like that, or that God somehow created the universe using the laws of physics as we understand them. Historically, scientific thought and religious thought were often united and people pursued science and philosophy due to attempting to understand God (like many Islamic scholars in the 7th century or like Renee Descartes who ultimately sought to prove the existence of God by pure reasoning). Science as a complete system of belief without some religious aspect is actually a fairly recent phenomenon that likely had very little to do with any particular scientific discovery.

Indeed, science can do very little to explain why things happen. It’s great at explaining how - e.g. science is great at explaining how fire burns or how a calculator can display an answer but it can be iffy on why. Now, “why” fire burns is probably more of a malformed question like what’s north of the north pole but we’re human, we like to ask why and seek purpose. Meaning makers.

The decline of religiosity wasn’t really driven by science showing biblical stories weren’t real, it’s a process driven by material reality and class relations. Although many people considered themselves Christian or religious in the west, they were very Deist and didn’t think God had much influence with the world apart from answering paradoxes like what was the primum movens etc.

Going further back, religion wasn’t a choice or something to reason to - it was just your life and your community. In medieval Europe, you didn’t really reason your way into a system of beliefs they all tied together into an economic system called the feudal mode of production. You just were a Christian and so was everyone you knew. Maybe some monks debated some esoteric aspects of theology but most people just lived their lives. This lasted for a while through to the Enlightenment and the emergence of capitalism in the 17th century. Except for some malcontents and rebels, people still didn’t reason towards being Christian, say. It was just your life - more like a hangover from that older mode of production and social cohesion than something necessary to maintaining capitalism.

Fast forward to the actual decline of religiosity and rise of spiritual none-of-the-aboves and nothing-in-particular. This was a process started in the mid 20th century (not really in WW1 which was conceived often as a holy or religious war by the soldiers and officer class including miracles and appearances of angels and so on). In reaction to the rise of consumerism and individualism - now religion became a choice or affectation! This is where we start to see the irreligious begin their massive growth but especially by the beginning of the 00s. It’s tempting to say Quantum Mechanics, GR, a scientific basis for cosmological origins like the big bang are responsible for the loss of religion - but in my view, these just coincided due to a third cause (that of economic changes and the settling in of mature capitalism).

Letter from Charles Darwin to Asa Gray (22nd May 1860)

With respect to the theological view of the question; this is always painful to me.— I am bewildered.— I had no intention to write atheistically. But I own that I cannot see, as plainly as others do, & as I shd wish to do, evidence of design & beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent & omnipotent God would have designedly created the Ichneumonidæ with the express intention of their feeding within the living bodies of caterpillars, or that a cat should play with mice.

Do we really need a scientific discovery to prove an existence that doesn’t exist? I think the proof that’s required is proof that God does exist and until that comes about, religion is clearly just a man made construct for the purpose of power and control.

Besides, I’ve given clear scientific examples to religious people before and they simply stated that it exists that way because god created it that way which is just the dumbest fucking thinking imaginable. You can’t help those people.

Sanitation.

Religion exists for a number of reasons, but the primary purpose it serves an individual is as a foundation for their overall worldview.

“Faith” as many call it, serves to answer questions we don’t have answers to.

Where did we come from? Why are we here? What happens after we die?

Religion gives us comforting answers to these questions, and as these questions are ultimately unanswerable, can do so in perpetuity.

Religion has also tried to answer questions that we didn’t yet have answers for.

What are the sun, moon, and stars? Why are there tides? Why does it rain?

God was long accepted as the source of these things, and prayer was thought to be the best way have any influence.

But today we have answered basically all the major questions. We have a working model of the entire solar system, down to the weather on other planets. We figured out how to turn rocks into computers. All that’s left is the unanswerable.

As for where we come from, we’ve filled in a lot of gaps. Evolution is now the accepted answer for where Humans came from, now the question is where life itself came from, and if there’s life outside of Earth (and how much).

Philosophy has given us plenty of options for what our purpose is. There are plenty of ways to wrap your mind around your own identity without turning to the supernatural.

And our study of anatomy and neurology suggests that our conscious self ceases to exist after death, the only thing standing in the way of that belief is the very human tendency to be in denial of our own mortality.

Religion is deliberately non-falsifiable. No matter what scientific proof you can come up with, at the end of the day they just say God is fucking with us burying skeletons of creatures that never existed and such.

The fact that it needs to be constructed that way is frankly all the proof I need to toss religion in the garbage, but everyone isn’t so cavalier about the disposition of their “immortal soul.”

Honestly immortality and the very nature of God are both abhorrent to me. If religion were true, the best I could hope for is to be cast into a lake of fire and be destroyed, so I kinda win either way. Worst case is all religion is wrong but so is atheism and I have to spend eternity with an entity who is less of a malicious cunt than the Abrahamic god.

What weakened religion is a long process going from the middle age to the modern world. It starts with the pope wars. It peaks with the religion wars in the XVIIth century. By this point the religious power was a political power like any other, but merely with a cultural hold on European populations. Which was the nail in the coffin.

During this period, the Church radicalised itself as a defense mode. Which solidified the laïcal mindset of the Lumières. Basically the church entered a cultural war against science because it feared it would lose controle.

Then the XIXth century happened. Monarchies got destroyed. And the Catholic Church got humiliated and destroyed as a political power. Socialism and communism appeared, and to state how progressive they were, they put the church in the same reactionary bag as the royalists.

In the middle of this are the liberals who don’t care much about anything but profits. Si when democracy is on the rise, they are democrats. When royalty comes back, they praise the king. At least as long as they let them make good profits. And that’s what the church doesn’t let them do. Morale goes in the way of profit. It forbid slavery and exploitation. It’s against science. It promotes charity. That sucks balls for the liberals. But order is good, so why not being a believer but without the problems?

It’s not science that made religion recess. It’s bad political decisions and alliances. Many renowned scientists were believers. Many still are. But somehow the religions are rejecting science because it doesn’t go into litteraly what their old fantasy book wrote. It’s a shame because religions could easily make a humanist evolution if they had the political will to do it.

The most reliable way to lose faith isn’t through science, it’s reading their holy text.

In general, nothing about science ever shakes a theist’s faith, and I doubt it ever will. Reason being: the moment science breaks new ground, religion retreats further back into the unknown. As long as there is an unknown, theists will have something to take shelter from.

‭Psalms 19:1-2

“The heavens are telling of the glory of God; And their expanse is declaring the work of His hands. Day to day pours forth speech, And night to night reveals knowledge.”
