Is anyone claiming to have definitive answers?

I've stopped believing in Christianity because the things I learned about physics and sociology far better explain the evidence that I've seen. Others appear to have done the same. Whether their is some untest-able higher power is irrelevant to my life. And if it can be tested and falsified then given enough time and effort it will be proven. Yet centuries of human effort have been wasted exploring what may simply be a side effect of overzealous agent detection.
