The history of faith with its countless contradictory beliefs, religions, ideologies, testifies that faith is not a reliable means of discovery or determining truth.
Maybe science isn't either? Once science had only four elements. Now the periodic table is open ended. And for how many hundreds of years were Newton's erroneous laws all but worshiped. Science is complete they said. It's easy to cite mistakes made along the way and sophistry to cite them as proof of something. Except humans make mistakes in all their endeavors.
And there is plenty of evidence starting with the high improbability of anthropic conditions which you seem to dismiss because they don't offer an ontological certainty. Or maybe it's just that they don't fit your desired result.
Science is self correcting and does not claim to have all the answers. The discoveries of science are proof of its efficacy and its ongoing investigation into the natural world.
