river-mouth civilizations... A human history time-line.
And you know what comes out of rivers these days. (Well, nothing much anymore for a lot of them, but that's beside the point.)
If I have this time-line correct: (A?) comet hits Quebec ice, makes (minnie) ice-age, (glacial lakes release?)
Forcing a new food chain on humanity thru climate change.
The ice-age lowers water levels + farming explodes in (exposed) deltas.
The melt 1000 yrs later drowns our (proto. HA!) civilizations (India, Florida, etc)
The river-valley nonsense well underway 5000 yrs later (after settling where migrating herds cross rivers. Middle-east antelope, ie.)
1000 ad, Viking square the circle by settling continental NA. (the crusades, marco polo etc)
Around 1400 first global pandemics release European exploration-craze. (black death, measles, syphilis.)
(china's junking around,+ puritan (hello cromwell. what else did you do?) settlements. Eventually.
Cute. Today's little globalization effort is a economic and not cultural rationalization?
And tin-foil hats block signals, making them illegal?
? So where are the ufo's already?
drat, I was doing so well there for a moment....
