Those who have no science and no chance of acquiring some, like to whine when there is change.
By requiring certainty, they insist that change in the perceived certainty of settled science proves their ignorance to be correct
Science, any REAL science, is never settled. Because human beings have only fragmentary knowledge of the Universe, there are exceptions and surprises behind every assumption and conclusion arrived at by the sometimes blind fumbling of trying to apply rules where chaos exists.
