If everything has a purpose then evil doesn't exist

[Anomalocaris]

Noah didn;t know and god didn’t know,

 But that’s because both Noah was the figment of the imagination of people who concocted the flood story probably during the late Stone Age,  whose tale was then stolen by ignorant Bronze Age hucksters who made up this Yahweh character , so neither yehweh nor Noah would have known what people who were probably ignorant even by the standards of the Bronze Age happen to not know.

you are aware that over 700 cultures record a great flood and the world being saved by some sort of great ark/noah type right? When 700 hundred culture from all over the world all retain and retake a singular narrative it become more than just a camp fire story.

Over 700 culture telling it in no ways makes it true in any significant way, much less literally true.    Camp fire stories gets passed around, until if it had a grain of truth, that grain became largely invisible behind the bullshit accummulated by people who don;t really even have a clear understanding what facts actually  even means as a concept.
