Science works in the opposite way to religion - skepticism and doubt are at the heart of the scientific method. Science is about coming up with a model or a theory to explain something, and then testing it and trying to prove it wrong. Most religions claim to know some divinely inspired truth which must not be questioned, and doubt and skepticism are seen as the enemies of religion - and quite rightly so.
The level of "faith" required to accept a scientific finding is not comparable to the level of faith required to believe in religion. If a team of scientists conducts an experiment and comes up with a result then the experiment is analysed through peer review, and if possible the experiment is run again and again (often by different teams) to see if they get the same results or not.
