Far more to this history will eventually out, politics or not, you can't stop discovery forever. Even controls over funding do not stop progress.

The mass migration of humans out of Africa circa 70,000 years ago is usually attributed to a combination of climate and environmental changes, cognitive and technological advances, following food sources like migrating herds, the discovery of coastal and marine resources, and population pressure.

It's interesting to ponder what motivated those earlier human forays out of Africa if the above factors weren't in play; strife, necessity, opportunity or curiosity?

All those things and also something much simpler… the carrying capacity of the land.

It's quite wrong to form an opinion based in current modern assumptions, the very article @PaulP links is an example of that, desserts now where forests used to be, and a total population that was just a fragment of what it has been for most of modern history.

That would be a factor with the migration that took place 70,000 years ago, but the earlier excursions happened during favourable environmental conditions and when the human population was considerably fewer.  Putting aside my evidence-based archaeological method, I'd like to think that it was curiosity and a sense of adventure, or perhaps even a dash of wanderlust, that motivated those ancient folk to head off into the unknown.

Then there's the earlier departures from Africa by Homo erectus, Homo floresiensis, Denisovans and Neanderthals, with only the latter two having the cognitive and technological prowess to rival modern humans.

This is where a Tardis would be handy  :)

The old sins, greed, gluttony, desire all wrapped in hubris, the tale had to have deep social origins somewhere!

The apples are sweeter over the hill, and there is no more basic craving than to want something somebody else has already got!
