We have pictures from space of a round earth, and yet there is actually a contingent of people, mostly American right-wingers, who insist the earth is flat. Belief will fill the void left by a lack of knowledge, and there is no limit to belief if it receives no push back from authority.

America gives the people an unusual amount of latitude in their beliefs, but it also separates its governance from those beliefs and gives authority to its representatives "as long as they don't use those beliefs in ways detrimental to the public purpose" as defined in our founding documents.
