Daniel Everett was a Christian missionary who was de-converted while living among a Brazilian tribe he was trying to convert to Christianity.
The tribe had no creation myth. They didn’t believe that the world had been “made” at all. They didn’t talk or think of such things.
When he told them he had “found Jesus” after his step-mother committed suicide, the tribe burst into laughter. “She killed herself, how stupid,” they replied. Instead of his experience causing them to accept his god, they found it amusing.
