Simply declare the object:

#declare two_balls =
    union{
        sphere{<-5,0,0>,5 pigment{Blue}}
        sphere{<5,0,0>,5 pigment{Red}}
    }

When you wnat to use two_balls:

object{two_balls }

You can include transforms such as rotate and translate in the object
statement. If your spheres are not pigmented in dividually or in the union,
you can even apply a pigment/texture in the object statement.
