[The Thing] How could the Thing take over the Earth if it only possesses one entity at a time?

The Thing can split, or so the documents we've recovered state. An American arctic research station and a Norwegian one both encountered the entity.  In both cases The Thing was killed only to surprise the surviving members of the outpost by re-appearing. The Thing must only inject even the slightest bit of its biology into our own and then it begins the rapid process of biologic conquest.
