If it was markers, it would be for a speices already on the planet, because offworld in space, they'd have electronics and other means to navigate.
I would make more sense that it was markers to highlight a certain place and point in the sky at various times,
For all we know though, they could of been ancient transmitters to these places they match up with.
There might be another reason many ancient monuments point to these same locations, maybe long ago the light was visible from an ancient war or
natural events and these were built by our ancestors to mark them.
It's fun to wonder, keeps the mind strong.
