When I look at both pictures, it seems as though the shape of the rock was there before it appeared ... almost as though it oozed up out of the surface. (Note: I know this isn't at all likely or even possible and just think it's an interesting trick of the eye)

I thought a similar thing, imagining mud getting squeezed up between two rocks.

I have to admit I laughed at this: "Only two options have so far been identified as the rock’s source: 1) The rover either “flipped” the object as it maneuvered or, 2) it landed there, right in front of the rover, after a nearby meteorite impact event." So, you know, our leading theories are that either the rover did it somehow, or, approximately 8-10 orders of magnitude less likely, we just witnessed a meteor strike…

What else could it be?

"Rover did it somehow", even at a remove or two, isn't exactly an unsatisfactory explanation....

I'm still pulling for either Marvin the Martian, or some kind of Martian Troll throwing stones from across the plain.

You're close to what I was imagining. I was thinking it's martians having a good time at our expense! "Watch the silly earthlings study this rock I'll put in their picture, lol!"

Earlier quoted context omitted.

Earthquake. Oops, crap, no, um ... Mars-quake.

I guess, but I would hope that would've been detectable.

It also would be quite remarkable since Mars is tectonically inactive at current state of knowledge.

> Really, nothing in between those two?

Well the first thing that came to my mind when reading the title was the phenomena of moving rocks in Nevada [1]. It could be similar but unlike them this doesn't seem to leave any trails.

That's how scientists work, they figure out the possibilities, and work with the evidence from there. It's not done by guessing what's more probable, and you don't eliminate a possibility immediately just because it's less likely.

The objection is to the thought that you can eliminate the impossible. Because to do that you'd need a lot more data and a much better imagination.
