I know you're just trying to prop up your own beliefs. Been there many times before it all clicked. I get it.

But let's be fair. Let's look at this with at least a hint of honesty.

Did religion enable us to create transistors? No. It can't. Scientific research into theories of physics brought us, over the last few centuries to quantum mechanics. If not for the many researchers and the scientific process there would be no Internet for you to post this on.

Many other scientific topics have, over time, also been incrementally improved, on average, resulting in most of the things we take for granted, whether that's roads, cars, medicine, clothing, etc.

Gps satellites wouldn't exist without the general theory of relativity.

Antibiotics wouldn't exist without discovery of microbes, penicillin, etc.

Evidence and sound methods are required to find out how things work, to develop, test and refine theories. That's how you avoid the pitfalls of cognitive bias (goofy, irrational thinking everyone is prone to) and gain a better grasp of the truth.

The Wright brothers successfully flew because they applied the scientific method and lots of testing of different designs and scientific hnderstanding of aerodynamics. They didn't get the airplane from religion.

Now, let's also pose your question with regards to religion.

Does Christianity, say, have a reproducibility problem? Or more to the point, is there one denomination or many?

Several at least, with fairly crucial differences in beliefs.

Can you provide any evidence to suggest the number of denominations is decreasing? That belief is heading toward a single interpretation?

I suspect no. Because as far as I know it hasn't shown any signs of this in the past 100 years.

Because there is no mechanism to definitively find the truth. No experiments, no evidence, no tests.

Generally, science (the processes and mechanisms) are designed to revise and refine our models of how things are so that, given time, humanity achieves a clearer understanding. It may do so in fits and starts with occasional steps backwards and stumbled (like the ether theory). But scientists have a proven set of tools to arrive ever closer to the truth. That's easy to see just by looking back at the state of technology and scientific knowledge 100, 200, 300 or more years ago.
