It can be shown by objective, verifiable, scientific evidence that, arguably the three biggest stories in the Bible – the Creation, the Flood and the Exodus – didn’t happen.
Seriously, the Creation story is told as two different, contradictory stories with different events and different timelines, plus it violates everything we know about cosmology. And who’s the narrator in the Creation stories? Was there a witness to those events? Whose word are we taking for the accuracy of these stories?
The Flood story is copied straight out of the tales of Gilgamesh; boat, animals, rain, dove, the whole thing. The story was simply swiped from an older myth.
In Exodus, the Bible says that there were 600,000 Jews or 600,000 families, depending on which translation you choose. That many people, hauling their possessions would make up a line that would stretch to China. I mean that literally. The line would stretch from Egypt to China. Ancient camel caravan trails are detectable from orbit, but there’s no sign that a huge mob wandered around that area for 40 years. They would have left evidence. Lots of evidence. There isn’t any.
You can find some “universal coherent message” in there if you’re looking for it, but it’ll only be your interpretation.
