Eyup Mr. TE sir ;)
I guess it's possible, but unlikely.
I reckon, leaning towards optimism, 25% possibility of the larger set of circles being rock art. The smaller bits do look like lichen traces. But the bigger ones seems to have a bit of depth in the lower left side. The lack of cups would make it pretty unusual, and like KK says, the depth seems a bit on the shallow side, though there's not much to go on there for a sense of scale. It'd be useful to see more photos, especially some where the surface is wet.
