Why build an Ark?

[Anomalocaris]

Not caring to know better is the point, even when told by intelligentsia.  The story, as told, only works when you do know better.

If you dont know better it's not interesting, you forget it.

no, it works just as well if you don’t know any better but succumb to the lure of the benefit of pretending you do.  Then you will take care to craft your pretense so it would not be easily penetrated when you really need to do the pretending.
