In fact, so prosaic a course of study like Euclidean Geometry was "designed" by Greek mathematicians who also designed several other systems of Geometry.
They chose to push the "Euclidean" form because it was relatively easy to understand (in an intuitive sort of way), and therefore easy to teach.
Still, it does not represent anything in the real world, and fails to recognize the curvature of space/time.
I am sure the kids would love that -- lotus eating all day while contemplating the Nature of Things, rather than that dry foundation stuff.
And the rest of the world will, of course, completely destroy what small lead in science and technology we have been able to hang onto despite the anti-science Luddites.
