How come several great civilizations all developed independently in a relatively short span of one another after thousands of years of primitivism?

>relatively short
>2000 years

>250,000 years of human existence
>All over the world develops civilisation within 2000 years
Yes, that's relatively short, do you know what relatively means? It means in relation to a given factor.

I think it was to do with growing population sizes in these quite fertile regions. A little less harsh than other regions, they allowed the populations to grow to a point where different groups had to cooperate and find some form of alternative method to survive as they could no longer all be nomadic hunter gatherers in these regions.

>Celts

merchants , trades , exchange of goods & technology
a middle school kid would understand this

They did not develop independently (although, they did made some independent advancements, like writing for example). Most of the fundamental Civilisation kickstarters, however, were created at a single place, but converged in those 3.

And this answers a question. Eurasian humanity has accumulated a critical mass of technology to enable a societal shift.

But didn't central American civilization develop completely independent at around the same time?

And they were forever crippled by not having access to some of those, most notably horses and chariots.

End of the last glacial maximum created ideal conditions for all these proto civilizations to form globally and so they did.

agriculture

How come early civilizations were all non white?

Sumerians may have been Finnish. The words for brain in Finnish and Sumerian are remarkably similar.

So they're mongolic

And they were forever crippled by not having access to some of those, most notably resistance to Eurasian diseases

fixed it for you

early agriculture needed a hot climate, hot climate = brown people

Pppppfffff

Because as you have correctly assumed, it's not the first time.

Their was a global civilization between 35,000 and 11,600 years ago. Farming has already been discovered from 23,000 years ago in Canaan and accepted by mainstream archaeology.

Which is a funny excuse because the greatest civilizations had collapsed and were already buried by nature when Columbus arrived

>all developed independently
they did not,
they influenced each other
you can walk from Europe to China and people did

Ancient Egypt was Black and Shang was Yellow

>you can walk from Europe to China and people did

Don't downplay how difficult that would have been in 3000 BC.

Also food for thought.

Göbekli Tepe is thought to have been created in its earliest parts around 9000 BC.

At the end of the ice age people were able to create large stone monuments. At a time period equal in distance to the pyramids of Giza as to the modern day.

Gobekli Tepe ruins any mainstream narrative of history. Civilization is a lot older than we thought, it was not built by nomadic hunter gatherers.

rise of nordic aryan people across the continents

gobekli tepe is not civilization

They also did it on a hill with no drinking water

A fairly sizable population was working on the carving, a bunch with the moving and others cooking and bringing water to sustain an effort.

A level of sophistication typically not known for what is ostensibly still the stone age...

How about you give a solid proof to your absurd claim or kindly fuck off. Fucking whites trying to take credit for everything

I'm an unironic Aryan supremecist but brown people built civilization first

Sumerians were Georgian invasors, its proved al ready.

>Which is a funny excuse because the greatest civilizations had collapsed and were already buried by nature when Columbus arrived
Yeah, well all civilizations ebb and flow, but not all of the get invaded by hordes of settlers around the time that their population had just been inexorably crippled by insanely potent disease for which your people have no evolved defense

They could not have built that without a stable sedentary population. It is a massive fucking project.

You completely missed my point. The Mayans had collapsed so long before Columbus that their pyramids were under hills of dirt.

End of the last ice age. Climate change following the end of the ice age shifted where the "habitable belt" was for humanity. Where was livable before is too hot and dry, so humans had to move and leave whatever they had behind.

It just so happened that the new habitable latitudes had the Nile, Tigris, Euphrates, Indus, Yellow, and Yangtze rivers, which supported enough high-density agriculture for civilizations to form.

well black and yellow are not white, also egypt had few black folks

Yeah, a few pillars... Give me a break

yeah they weren't sedentary but they weren't full nomadic HGs either, that area was full of wild wheat and whatnot so they were pretty much in a transition period

Not him but because the neolithic revolution didn't start until 11,000 to 10,000 BC and before that you didn't have agriculture producing a great enough food surplus for advanced societies.
So it's not really 2,000 out of 250,000 it's 2,000 out of the last 10,000, which means two millennia is still a long time considering the circumstances.

Example?
America seems to be similar relatively to the middle east.
