There are flood stories, true. Passed down orally. We can speculate on glacial dams breaking, earthquakes, lots of things. Mother of all tsunamis from a meteor? All within the last 5000 years? There is evidence of huge inland seas, but part if that evidence is a shoreline.
Some of the related stories dont fit. Mature olive tree? Clean animals defined before the law? Tower of babel having a huge population in 200 years? (Rabbits!)
My take on pyramids/ minarets is a migration for unknown reasons converging, disagreeing, and dispersing. Post Columbian records show a mobile society in america pushing each other out. Same for the world, look at DNA dispersal.
Once I thought I would ask resurrected people about it.
