Mankind developed slowly, and then all at once. Anatomically modern humans first appeared some 200,000 years ago  ... yet the world’s first known civilization of Sumer didn’t begin until 5000 to 6000 years ago. 
Those experienced in humans may not be shocked the brutes didn’t play to potential way back when. It’s possible to see lessened glory in a species prone to such epic stagnation, but division-of-labor and retention of knowledge are surely advanced concepts that took eons to learn. (They are not so perfectly practiced even today!)
Horsemanship began with Civilization ... or vice versa
Whatever the reason for the delay of civilization, a great change took place at the time of its birth: the advent of horsemanship. The quirky, panicky and potentially dangerous animal somehow became more than prey in the eyes of early civilized man. Much empathy is exercised in handling horses—since the skill is also required to sustain civilization, perhaps this is why they began together. Empathy is a civilized art.
Horsemanship is more than a foundational skill: in all times it has flourished or decayed according to the state of society. In all times, also, horses have returned investment in their care and potential. People and horses are partners in the joint venture project of civilization and we rise and fall together.
Still Alive and Growing
The value of horses in our motorized society is often underestimated, but the horse has always been more than horsepower. Since first painted on prehistoric cave walls the animal has inspired our better journeys, a gift that can never become obsolete.
Today horsemanship is alive and expanding, and continues to advance. An important NEW value of horses is to keep alive a founding force in civilization. As a seminal art that continues to mirror society, horsemanship is a valuable legacy to preserve for future generations. This can be done! Horses are not necessities in daily life today—but horsemanship has taken many engaging new forms in recreation, sport and therapy.
Amazingly, horsemanship thrives even in our modern technological age. As long as we have horses, we are keeping one of the founding fires of civilization lit.
