>>> Cultures around the world have “oral traditions” of a worldwide flood. Still people don’t want to believe it.
Perhaps in part because none of these ancient peoples would know if the extent of their observed “great flood” was global or not. No satellite views, no telephones from the next continent, no info at all beyond what they could see from their soggy perch.
Floods aren’t rare. Biblical deluges are.
But sometime look up the sketchy info on the great meteor that apparently fell in the Indian Ocean circa 3000BC. The tsunamis from such an event could tie together many of these stories in Africa, the Middle East, India, and South America.
When a flood seemingly goes on forever and is much worse than normal flooding in your known ‘world’ that may extend only a few miles from home, you’d describe it to younger generatios as something akin to a God-driven “global” flood too.
Any I was taught to revere my elders and what they say.
