According to the text, why were Galileo's initial empirical observations insufficient proof against the established order?

The resistance was partly due to the method of persuasion; the observations were compelling but did not immediately nullify the entire established physics supporting a stationary Earth by providing the overwhelming mathematical proof demanded.
