For serious discussion of the controversies, approaches and enigmas surrounding the origins and development of the human species and of human civilization. (NB: for more ‘out there’ posts we point you in the direction of the ‘Paranormal & Supernatural’ Message Board).
More on the tunnels, and the sort of mining operations that probably took place there, going back to Roman times and possibly before.
