You seem to be saying that there is nothing that leads to truth, but science.
Science is just a method to verify truth claims. How you come about that claim is up to you. You can make any truth claim you want by whatever means you feel is appropriate. Einstein, for example made a number of claims about time and space. Science has been able to validate many of his claims. SInce these claims have been proven by science, we don't have to rely on his word.
If that's the case, you are the right place.
Science depends on a system of trial and error, where oftentimes it proves to be a fruitless attempt at finding truth.
The misses are often hits, that then have to be counted as a miss. To depend solely on science, to find truth, seems like a never ending quest.
Partly, theories/hypothesis are based on what we know to be true or what we accept to be true. Everyone does this. Folks observe reality and make a guess at how it works and reality may seem to work according to that theory. Someone may observe that whenever a car engine is running it vibrates for example. They come up with a theory that vibrations makes the car run. What science adds to this the attempt to disprove such a theory by eliminating every other possible cause. In the case of a car, maybe remove gas, air, electricity. Just vibrate the car and see if it runs. If the car still runs with vibrations being the only possible cause, then you've validated the theory.
Because the physical man sees spirituality as myth, they fail to see how far behind they are.
We don't need science to verify truth of everything. It can't.
Oftentimes, what man thinks he has verified, is just another belief like the other person.
Because they haven't actually used science. They only did the first part. Came up with a theory, which kind of seems to work without eliminating all other possible causes to prove the truth of their claim. Without doing this second part, then people can claim anything that seems to be true as truth whether it is actually true or not.
Knowing what doesn't work is just as important as knowing what does work. Science does miss a lot. It's part of the elimination process. To arrive at the truth, you need to eliminate everything that can be determined not to work.
Here we see how science is a sacred cow for many.
Science, used properly is simply a tool to eliminate false, claims, theories, hypotheses. If you don't go through this process, you can't really know if you can trust the claim, theory, hypothesis that you are relying on for truth.
