Your scientific conclusion may indeed be correct. By contrast, tenets or beliefs that are based on faith fall outside science. They are not subject to disproof by new information. Such faith-based beliefs typically only change as a result of force or revelation. Science offers no absolute truth, no absolute certainty.
All conclusions are tentative.
Unanimous agreement for a long time is no guarantee of truth. For centuries, no one had the least idea that the continents had moved around, split up and crashed together again during the course of earth's history. Yet, evidence gathered mostly during the last fifty years indicates that they have indeed done so, and satellite lasers now permit us to measure the ongoing movement directly. It took Einstein's theory of relativity to dismiss the need for the ether, and high-powered rockets to document the vacuum of outer space. Einstein's theory also modified Isaac Newton's laws of physics, which still work fine for explaining everyday phenomena, but do not cover every circumstance.
