A modern person interprets this as a sky map. But it some round and cresent shapes on a field of dots. Not sure they drew the sky like that in the Bronze age? What evidence is there, that it's supposed to represent the sky?

The stars are no evidence. A bunch of dots can be stretched to fit any star configuration you please.

And there are way too many crescents. What, did we have three moons back then? And none of them are shaped anything like the actual moon looks at any time.

Hm.
