Why were nomadic Native American tribes in California unable to develop advanced technological inventions at the same time as Mesopotamia?

Agriculture was not as successful as a method for producing food as it was in the fertile Mesopotamia area. Contrary to popular belief, agriculture was practiced in North America, but the soil would not yield as much food as today, The key to the success of agriculture in the California area today is the profound adaptation of the soil in order to render it fertile (use of fertilizers and heavy agriculture machinery) plus the construction of an extensive irrigation system.

At the time the Mesopotamian civilizations developed technological solutions to their everyday problems and tasks (around 3,000 and 5,000 BC), the native tribes inhabiting California satisfied all their needs using the same technology they had been using for thousands of years, so they did not deem. developing radically innovative solutions for the same tasks necessary. This cannot be attributed to a lack of ability or ingenuity by the native tribes. A clear proof of the adaptability and skill of the native tribes is the domestication of horses within 3 generations during the seventeenth century.
