The scientific method is the best means we have of approximating any sort of objective truth. Peer review, repeatable experiments, refutable prediction, reliance on physical rather than persoanl anecdotal evidence etc. etc. are all designed to nullify prejudice, bias and belief when drawing conclusions. The scientific method in it's widest sense is our best effort to peer over the top of the tinted spectacles we all inevitably wear.
If you have a better method for reaching the most objective conclusion I am sure we would all love to hear it. However....
This discussion may be better held in 'The consequences of evolution is false' thread, where we have reached the same sort of point.
