> that whole aspect of replication along with that "scientific method" thing
So uh, religion has been replicated quite a lot. We have historical records of it. We've seen an unprecedented revolution from religion, including science. And we've seen our pinnacle of civilization beginning to collapse since most people abandoned God. How much more proof/evidence/anecdata you need? We still track time in years since Jesus was born. That was 2024 years ago.
> even if this phenomena was something that only humans could observe, it would still be testable with science.
This is a belief. The belief that there exists nothing in the universe that cannot be tested by science. But science is filled with untestable things. Mind-numbingly humongous leaps of pure speculation about something that makes no sense and cannot be measured. Like dark matter, spacetime singularities, or "the big bang".
Science can't even measure consciousness! Or do you take IQ tests as gospel?
