Looks like a motor protein. But it's probably really fast or super slow in reality. This render has it at a normal walking pace, but renders are almost always wrong.
Whatever it is, it was necessary to create complex life that would observe it. No matter how complex or convoluted something is, just know that it was designed so anthropogenic observation could be made. There is no such thing as coincidence. The stars, the planets, every asteroid and comet, the culmination of all evolutionary decisions, every protein and virus, every bomb and bullet in every war, nothing is random, but necessary.
