I agree it is in many regards "stone-headed", For example, the belief that a four footed wolf-like land animal, morphed into a megaton of blubber...
...and the belief that apes became human apes...
... all are based on insisting that that particular belief is correct.
Yet there is no account of a single common ancestor. There is no account of a gradual transformation, etc.
However the guess does remain that a few bones paint a very accurate picture of how we got here. Not being able to see that, would make it a blind guess... ant they claim it's correct.
It seems to me that no one actually says there are things that are not known, and leave it alone.
It seems humans have a built in system to know things.
They want to know why they are here; where they came from; where they are going. Hence science. Hence ideas. Hence investigation. Hence religion.
I propose that the why, what, and where questions were a product of man from his beginnings.
What do you think?
