Yes, if you look in the Guide to Standard Mathematica Packages, you'll
see exactly such a primitive under Graphics`Shapes`. However, note
that the arguments for Sphere are not Sphere[x,y,z] but Sphere[r,n,m]
where r is the radius, and the sphere is drawn using n(m-1) polygons.
If you want to move the sphere to another xyz coordinate, you have to
use the TranslateShape function, which is also in the Graphics`Shapes`
package.
