No that is stupid. Ancient people were not idiots, they are able to learn from experience and make observations about illness without having a full understanding of the germ theory of disease.
No matter how much you post this, science and religion remain polar opposites. Religion detests science, because it proves the impossibility of god(s). You can't get past that, so you make dishonest claims like this one, to cover the other dishonest claims. Lie upon lie is religion, constantly needing to lie to cover the other lies. Where does the lying stop? The grave?
