There are only so many simple shapes to carve in rocks, and all cultures across the earth carved ones that resembled each other's. Over times they developed into more complex and culturally unique versions (such as the Hindu/middle eastern style compared to Slavic or Celtic style embellishments).

Jung's (and others I can't recall names of) theories on this relate to these shapes and symbols either being related to our collective unconscious or to shapes that are naturally formed in dreams and trance states by the way the human mind functions. Anyone who has ever rolled or tripped with heavy visuals has probably seen spirals and other common geometric shapes appear, he'll you can even do this by closing your eyes, lightly pressing on your eyelids and keeping your eye muscles very still. After a short time dots, tunnels and geometric shapes will appear.

Another very compelling and fascinating tale on petroglyphs found across the globe is presented by Anthony Peratt here and I highly recommend watching this lecture! It is not some random YouTube moron, this is a highly accomplished physicist from Los Alamos presenting to a University conference.
