I just composed a well-reasoned and insightful post to this thread, only to be 'timed out' .
I lost everything I wrote.
I spent a lot of time checking references, thinking, writing, re-writing, trying to get my words to match my thoughts.
I can't tell if SGU Forums timed me out, or my browser, but SGU looks like the culprit.
The bare gist of my post was:
Evan: "Civilization" refers to people who live in cities. The Clovis people you were talking about had no idea what a city was. Please understand that even lowly Anthropologists try to be precise in their definitions.
