Imagine making a movie trying to prove a story from the Bronze Age. If just 200 years ago people still believed in vampires, try to imagine what people were capable of believing 3,000 years ago! Even if a global flood happened, there is no way for this myth, as told in that compilation of fragments of parchments from the Iron Age, aka Bible, to be true. And because of what? Exactly: This myth says that specimens of all the animal species in the world walked, flew (and swam?) to a boat that took a hundred years to build by a five-hundred-year-old man (so, he was 600, when he finished it), and all those animals spent more than a year on that boat. I mean, seriously! Add to that that the myth of the flood says that the god of the Bible drowned also old and sick people, mothers, pregnant women, children and babies. So, even if this absurd story were true, how could it possibly be a good thing? How could it possibly make someone see this god as a god of love, a god who deserves to be worshiped?
A very good book about all this and much more is "Liberated from Religion", by Paulo Bitencourt.
