You know, don't overestimate that "proving" stuff. I mean proving something comes from a system called science. That system is limited, it only works through empirical research. And the outcome of empirical research is ALWAYS subject to interpretation. More in-depth research often leads to less understanding, but it does gather knowlegde. I once talked to scientist who was really deep into brain research and he told that the more they reserach and test and try to prove, they find out new things that makes one throw out all conclusions of the past.
So proving in the scientific way is not a way to truth, it helps in gathering knowledge but not necessarily in gaining understanding or proving hypotheses...
