To be fair to the original “scientist” you can definitely go to museums and find rocks that are supposed to be tools with pretty much 0 indication visible to the lay person.

But that’s exactly why I wouldn’t assume that any rock was worked by human hands. Especially when there is a far greater chance that any given rock will not have been worked by them and is just a rock.
I will stand by my point that the one on the left looks like it would be unusable as a tool though.
