That's not a valid generalization. For one thing, you're overlooking the agricultural societies outside of Eurasia and Egypt. There were of course major agricultural centers in Mesoamerica and the Andes. One of the earliest centers of crop domestication was New Guinea. Many crops were also domesticated in the Amazon basin in South America.

The interesting thing to me is that crop domestication seems to have begun almost simultaneously between 11,000 and 9,000 in widely scattered parts of the world in quite different climates, just after the end of the Pleistocene at the end of the Ice Ages. Humans seem to have started to domesticate crops as soon as the climate stabilized enough to make conditions somewhat predictable in particular areas.
