Did you? Cause it’s an irrelevant counter argument. It presumes a system at rest. Which the earths crust is not. Land masses are constantly moving due to the external force of magma and super heated gasses rising from the earths mantle and penetrating the crust along the edges of certain tectonic plates. This force causes the entire plate (which is floating on more magma) to slowly shift. Sometimes away from an adjacent plate, sometimes alongside, and sometimes towards. 

Basic geology dude. Like even if you are 13 or whatever.
