Does the Thing actually have a home?

I see lots of posts about the Thing building a craft to either go home or infect the earth from warmer climes.

This supposes that it is an entity in its own right.

What if it’s a virus? Just spreading randomly through the universe, what if the ship wasn’t even the things, but just its latest victims transport? I know we see its attempt at building a smaller craft, but seriously, could it actually build an effective ship? It might just be a cargo cult offering or just a ghost of its previous incarnation. We’ve assigned intelligence to it, we assume it has a plan, what if it’s just spreading like a virus? No plan, just is.

I stand to be corrected or see others pick up this random thought that just popped into my head.
