People jumped to false conclusions, when agnosticism on the matter was a more rational choice.
A lot of people probably weren't aware of the cosmos and its nature, so to some of them the sun was nothing but its image. A sensible opinion, at the time.
I certainly agree that the more that is observed of a situation, the more we can know. So, to observe particles and forces, is to know more of these mechanisms. But that does not imply we know them completely.
