The actual specifics of how people lived were lost.

Just saying

Most of red sea used to be land before end of Y.D.

sahara did not exist

To my knowledge the Sahara cycles.

Well ok, _in Y.D._ it didn't exist

Agriculture as far as we know has only been enabled for the past 12-11,000 years.

Coinciding to the end of the Y.D

Which itself lasted just over 1,300 years which isn't long when we're talking major scale.

the issue is, there's very little archeological research being done in sahara

or on the seafloor of red sea

I'd imagine both environments would be somewhat difficult to excavate.

Yeah. Which means that the _as far as we know_ is ... limited

In the former you'd need a *lead*, you can't just dig up millions of square kilometres of sand and *hope* you find something no evidence exists for.

In the latter... it's covered by water. And still no leads.

there are the eye of sahara theories

and the south america theories

which do not seem entirely unplausible

But are the theories based on what there is actually indicative theories for, or just speculation based on what *could've* been.

The fact the Sahara was not always a desert does not mean the land was suitable for farming.

Most land wasn't until the earth warmed up *following* the Y.D

And even when we invented agriculture it took another five thousand years for the first city to emerge.

And civilisation generally.

Assuming that length of time before the Y.D you'd end up back in the Ice Age.

There are maps that show the Antarcitca, before it was discovered in 17th (?) century.
And the way Antarctica is shown there corresponds to how it would've looked before end of Y.D.

It's an interesting theory I'll grant you and perhaps humans did make some strides immediately in the warming period following the Ice Age which was cut off by the Y.D

maps that are allegedly copied from older maps

from alexandria

But it's not enough time to enable them to create a civilisation as I expect you're imagining it.

I mean for one the world didn't become warm enough for agriculture immediately after the ice age as we defined it ended

it continued to warm until the Y.D when it rapidly cooled for 1,300 years and ever since has been more or less continuously warming

And only then we did we get agriculture on any significant scale. And 5-6,000 years later, urban settlement like Eridu, Ur, and so forth.

I find it exceptionally hard to explain maps of Antarctica as it was in Y.D. without a civilization that existed at that period.

It wouldn't be the first time a landmass was added to a map that didn't exist.

Others speculate that the Ottoman map I think you're referencing actually depicts South America.

Old Worlders weren't even aware of the New World until 1000 AD-ish.

I find it suspicious that it would _randomly_ be so similar to Y.D. era Antarctica

And even then it wasn't widely known to exist until the dawn of the 16th century

Could you show me?
