From Feynman’s The Value of Science:

When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain.

Some distrust science because it seems to overturn itself and prove itself wrong. This is really a manifestation of its strength. Science is a free market of ideas and observations. Anything that doesn’t reflect reality is eliminated while the real stuff gets refined and improved (moving toward the center of this diagram) but never becomes dogma. There is always room for doubt.
