[null and void]

Recalling that the skies were much clearer in ancient times than they are today,

What??? With that antediluvian sphere of water up there???

some people (not all) could see the rings as if they were horns, or a scythe.

I rather doubt that, no human eye has the angular resolution needed to resolve that fine a detail.

I'd be more inclined to believe that an even more ancient civilization invented the telescope. Sadly that would push civilization back further than 4004 BC. Far enough back that not only were all physical examples of a telescopes lost, but the very concept of telescopes was forgotten.

Since the telescope was invented in Middleburg Nederland some time in the 1400s, we know the ancients did not, in fact, have telescopes.

On the other hand, your belief in the total uniformity of human visual accuity is highly disturbing. There is and has been substantial variation.

BTW, concerning the arrival of modern Iron Age man to North America, there's a really big problem on the East Coast ~ the soil is acidic enough that almost any chunk of iron (knife blades, ploughs, helmets, swords, guns) that fell into the soil 300 or 400 years ago is now gone ~ dissolved ~ ain't there no more.

Makes it difficult to do archaeology ~
