is a reason the Middle East was essentially the birth place of
civilization, easy tamable animals/beasts of burden and incredibly
nutritious and easily manageable crops. When people spread out to the
east and west, they followed pretty much the same latitude so the crops
could be grown in the same climate, this is why you find most major
civilizations just above or below The Tropic of Cancer. In many
other people didn't have access to the animals or the crops so they had
to spend most of their time gathering food so they could survive, unlike
in Europe or Central Asia or The Middle East where you had enough food
to not only easily survive, but support people who did other things,
like research technology. You must also remember that many "poor"
countries today were not so poor in the past and are only that way
because of colonization. Take the Aztecs and Mayans for example, huge,
powerful, rich and advanced civilizations wiped out by by a literal
handful of Spanish, or the African Kingdoms wiped out by French, Dutch
and British colonists. If you want to see an example of this happening in the modern day, this is a picture of a school in Afghanistan in the 1970s.
