The first thing that comes to mind when looking at the schematic it seems more like a creature hunched over and hugging their knees. I am heavily reminded of the robots from The Studio Ghibli movie Castle in the Sky. Their resting mode is a different form than their active form. So with the movement, maybe the "space craft" is actually a form they take to travel.
The closest analogous thing to Earth creatures would be like the sailfish, where its large fin can lie flat or extend to control its speed.
A video game analogy would be like how Deoxys can change forms and come across more strongly when compared to the movie movement.
I personally believe that we are the antient civilization that will confound and awe future life. But I am open for the possibility that we are not alone.
