Because there will never be a way to prove or disprove faith. Im agnostic, by the way, so I allow for the fact that I dont know everything and there very well could be a God. Scientific theories can be proven and disproven. The disproven ones get discarded and the proven ones can be refined and improved over time.
Science does not start out with assumptions, at least not accurate science. You are making the assumption that faith and science both fall under the perview of historical science, which is faith.
I just pointed out the incorrect and contradicting data of the article. I didnt mean for this to be some sort of huge debate.
==Because there will never be a way to prove or disprove faith.
Just as there will be no way to scientifically prove or disprove ones faith that the Universe created itself and everything in it. Both *assumptions* are philosophical/religious, and the only way to test them is to follow the standard tools of historical science which consists of multiple competing hypothesis, and inference to the best explanation.
