Try to do a YouTube search for footage of the live television coverage from the moonwalks, for example. Thankfully there are other resources, for that particular example, and YouTube is a over-taxed sewer at storm surge, but my point is clear enough.
A two tier system of awareness is developing where science is either mixed up with ghost stories and political agendas or highly specialized science conference papers. Thankfully, noticeably late in life, I developed an appreciation for the latter, though even there it's difficult not to get into a shouting match with scientists so sequestered away from politics they've become tools of the lobbyist industry.
In short, it's telling that modern search engines can't discover the difference between ordinary and extraordinary claims. Telling of what, I'm not entirely sure.
I'm inclined to be tolerant. At least they're looking at the images! I did find a comment that identified this one as 735MR0031500000403075E01_DXXX . There are some similar looking rocks in other images linked on the sol 735 Mastcam Raw Image page.
The "petroglyph" rock appears at the end of the SUBFRAME product section, and is actually in the last two panoramically linked "right" images there.
