Pressure finding form is good, but why base-60 specifically?

Base-60 is useful because 60 divides beautifully: 2, 3, 4, 5, 6, 10, 12, 15, 20, 30. It makes fractions and accounting less ugly. It survives in our minutes and degrees because good administrative tools can outlive empires. That is real lost tech if you want a phrase, but it is not machinery from a visitor. It is a durable convention.

And because sky cycles reward divisibility. You can be wrong about astrology and still see why a sky-clock civilisation would love 60. Please enjoy me being restrained.

I am enjoying the restraint with caution.

What about all the sudden inventions: wheel, writing, law, astronomy. That bundle is too much at once.

It is a bundle when seen from far away. Up close, the dates, precursors and functions differ. Tokens precede writing; wheeled vehicles have contexts; law codes grow out of custom and royal display; astronomy grows from calendars and omen practice. The summary "all at once" is a telescope. Useful, but it compresses distance.

And "no evidence before" often means perishable evidence, not no practice before. We have a preservation bias toward clay, stone and burnt accidents. The archive is not the past. It is what survived the past badly.

This may be a stupid comparison, but is it like seeing a printed book and assuming language started with printing because that is where the copies survive?
