“I thought the idea of a flat Earth was ridiculous,” said Robbie Davidson, a slim, hyper Canadian sporting a ginger goatee and loose fitting suit while sitting in the lobby of a Denver hotel.

“I’d first heard it in the Bible and thought ‘this can’t be true,’” he recalled, speaking with rapid excitement. “I mean, I believed everything else, that the Earth was created in six literal days, but what about all this other stuff [about a flat Earth]? To be consistent as a biblical literalist, I can’t pick and choose.”
