Dr. Bill would like to see me cut down one five foot thick oak with a bronze axe.

If I can haul out those stones from wherever and put them up I *ain' gone let a few pieces of wood get in my way†. If you don't think they hauled those stones from somewhere you might be hard pressed to explain how the dang thang got there in the first place.

†Hey, maybe the UFO pilots that gave them the antigrav machines they used on the stones let them use their laser cutters, too.
