(1)Wouldn't these designs be all over?, and showing up on imagery? . (2) Why is the design so weathered like an archeological find, and not sharp and crisp, like if the tool was recently used?
It isn’t. The scale of that is tiny, and close-in, and there’s remnants of the medium used to lube the drill, as well as tailings.
The alternative is, other than pareidolia and the stufff sent from Earth, the only traces of intelligent activity on the nearly airless Mars are some tiny little tooling marks that just by coincidence match those left by the Earthlings’ rovers.
