Thing is, that the inscriptions are very much modern, made within the past 100 years and possibly within the past 50 years.
The lines are bright and sharp and deep, not pecked into the rock, and are made with a modern tools (the tight angle of the curves reveals that it was
an implement with a small tip like a knife -- you can't do spirals like that with a blade that's very thick).
These are random symbols and are not language (for one thing, language is written along a line of some sort... either side-to-side or up and down).
To give you a better idea, here's a link to genuinely old carved language (Ogham... so the stone's at least 1500 years old)

And the Rosetta Stone (a detail), carved in very hard granite and still showing some wear:

This is a modern fake (based off ancient Hebrew, so the symbols are language in many cases) :

And at Inscription Canyon you can see petroglyphs that are over 5,000 years old... defaced with modern graffiti (like the cross):

See the differences? Those stones are modern and not ancient.
