I”ll see your Euclid and raise you Stonehenge. The English had geometry down about 2200 years before Euclid was born ;)

I think advanced thinking has been around since the first cooperative defense farm settlements allowed for some leisure time. Environmental catastrophe, epidemics, social constraints on free thought, invasions or war where every library was burned, all contribute to wiping out the knowledge base; the wheel has to be reinvented again and again and again from the ashes. England in the 1800s and America in the 1900s made great strides under an environment of free thought, just as Greece did in its time, and likely will again.

Hm........ April Fools Day passed more than 100 days ago.
In 2500 BC, civilization was cantered in the Mesopotamian Cradle among the Akkadians, Babylonians and Persians;
England and Englishmen didn’t exist and Stonehenge, whatever its merits, has never reminded anyone of the Parthenon.
The Internet, while a useful tool, is the spawn of every absurd and crack-pot nostrum that man can conjure up. Then instantly circulated w/o review or reflection by that gatekeeper of knowledge, truth and wisdom; the media, eternally needy of attention. Beyond ridiculous.
