Scientists have made errors in empirical, observable science as well, Monty. Ultimately, people with your belief set put the same amount of faith in the human mind that those who hold religious beliefs put in their chosen religion.
Despite the fact that there is overwhelming evidence of the limitations of the human mind. Remarkable really. Or, to put it another way, astonishingly arrogant and superficial.
I put no more faith in the human mind than you do when you have an x-ray and get told that that headache you've been experiencing is not in fact a brain tumur. The reason you breath a massive sigh of relief and walk home with a skip in your step is because you put the same amount of faith in the human mind that those who hold religious beliefs put in their chosen religion.
But we can, objectively, be far more certain that the Quran was written by a common-or-garden terrestrial being than that it was written by a bloke who flew to the moon on a horse.
Therefore, even if you consider they both derive from faith, it follows that we rightly consider those who believe the latter to be more stupid than those who believe the former. Because of the levels of probability at play.
If you define truth as the limits of human experience and knowledge observed through controlled experiment. Most people define that as science. Truth is something rather more elusive. Science is constructed to answer a question but never forget that somebody asked that question in the first place.
Remember, there was a time when we believed it was a universal truth that three at the back didn't work.
